Lost admin rights - install Canon software

I've been trying to install a Canon Digital Solutions disc, and keep receiving the same error - I don't have the necessary access privileges, please log out and log in as an administrator.
The account that I am using has full admin rights, and I have not made any changes to the computer since purchasing it, except for uploading software updates. The computer already came with v10 of the Mac OS, which appears to be a cause of a lot of the faults that I can find.
Can anyone help, I'm new to Mac's and don't want to start messing around with the back end if this can be helped. Of course, to make it better, I am not in my home country, and therefore don't have access any of my software discs for a couple of weeks.

All three show that I do have admin rights, in terms that I have the short name, then underneath have 'Admin' in the line underneath.
I have another account that is called Guest, which has the text 'Login, Sharing' so I assume that this is the access for each account. My apologies, all Mac terminologies are new to me.
I can 'print screen' (to use a windows terminology) if you can inform me of how this function works on a MacBook.

    box appeared "clean your mac" then lost admin rights in some files. How can i restore those rights?

    This sounds like you may possibly have been infected with MACDefender.
    Malicious software dubbed "MACDefender" (also goes under the name of MacProtector, MacGaurd, MacSecurity or MacShield) takes aim at users of the Mac OS X operating system by automatically downloading a file through JavaScript. But users must also agree to install the software, leaving the potential threat limited.
    The new MACDefender malware was first noted on April 30, 2011 by users of the Apple Support Communities, and was highlighted on May 2 by antivirus company Intego. If the right settings are enabled in Apple's Safari browser, MACDefender can be downloaded to a system after a user clicks a link while searching the Internet.
    "When a user clicks a link after performing a search on a search engine such as Google, this takes them to a web site whose page contains JavaScript that automatically downloads a file," Intego said. "In this case, the file downloaded is a compressed ZIP archive, which, if a specific option in a web browser is checked (Open 'safe' files after downloading in Safari, for example), will open."
    More details here:
    http://www.reedcorner.net/news.php/?p=138#more-138
    However, users must still agree to install the malware after it downloads. After the ZIP file is extracted, users are presented with the "MACDefender Setup Installer," at which point they must agree to continue and provide an administrator password.
    Because of the fact that users must agree to install the software and provide a password, Intego categorized the threat with MACDefender as "low."
    Users on Apple's support forums advise killing active processes from the application using the Mac OS X Activity Monitor. MACDefender can then be deleted from the Applications folder by dragging it into the trash. There is also a 'MacDefenderKiller' uninstaller available here:
    http://www.macupdate.com/app/mac/38520/macdefenderkiller
    On May 24 Apple issued this Knowledge Base Article on how to avoid or remove the MacDefender malware (which has been updated several times):
    http://support.apple.com/kb/HT4650
    But that does not mean it is over. On May 25, MacGuard is launched:

    Apple  released Security Update 2011-003 on May 31, 2011, which adds malware detection and removal for the "MAC Defender" scam and delivers a daily update mechanism for updating subsequent malware definitions. This is for Snow Leopard only.
    The security update for Mac OS X 10.6.7 is available from Software Update or the company's Downloads page. Installing the update does not require a system reboot.

  • I installed Canon software on my macpro laptop and it takes forever to startup and shut down

    Hello.  I recently got a Canon Rebel T3 and in order to download photos to my macbook pro I had to install their software.  Well, after installing it, it takes VERY long to shut down and start up my laptop.  Can someone help?  I already deleted the software off the laptop, but that hasn't seem to fix the issue.

    "... I already deleted the software off the laptop, but that hasn't seem to fix the issue."
    I doubt that the software was the issue. So why not tell us what model MBP you have and how much free space is on the hard drive. When was the last time you booted to the OS installer disk and run Repair Disk from Disk Utility? BTW, you may not need their software to download pictures to your Mac. Launch iPhoto and from the menu: iPhoto>Preferences>General: Connecting Camera Opens.....

  • Grant user admin rights, install itune, ungrant rights?

    On Windows XP, installing iTunes requires admin rights. However, it is not good to use an admin account for regular work. For the Palm Desktop, the workaround was to grant admin rights to the user account, install the application using the user-turn-admin account, then ungrant admin rights. Will this last step cause problems for iTunes, or does iTunes require admin rights for its regular operation (outside of being installed)?

    Actually, I can't find the thread! But the solution is that installing it as Admin still lets it be used by other user accounts, and each user account.

  • Lost Admin rights, can't change PW from install disk

    I just installed the update to 10.4.11 and my main user lost it's admin status. It was the only admin I had set up.
    I've found several articles including this one:
    http://docs.info.apple.com/article.html?path=ServerAdmin/10.4/en/c8od36.html
    which seem to address my problem. It seems like changing the Root Admin's password would fix everything however when I boot up from the install disk and click on change password I'm then supposed to click on my HD icon but can't because it's greyed out.
    It seems to be that my computer doesn't recognize any users, not even the System Admin (root). The only thing I can imagine (in my very small amount of mac knowledge) is that the there are no users listed in the admin users group in the computer.
    Any ideas at all that might help me fix this without having to reinstall everything would be so greatly appreciated!!
    Beth

    Hi Beth, and a warm welcome!
    I think you may have some corruption...
    "Try Disk Utility
    1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
    2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, *you must select your language first.)*
    *Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.*
    3. Click the First Aid tab.
    4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
    5. Select your Mac OS X volume.
    6. Click Repair. Disk Utility checks and repairs the disk."

  • Lost Admin Rights - Can't Boot from Install DVD

    On the first day I clean installed Leopard. Apart from one or two minor issues (since resolved with help from you guys) everything was working fine -- until now?.
    Today, I tried to update NeoOffice as I've already done twice since installing Leopard, but can't get beyond Administrator Name/Password. I only have my account on the machine, so popped into system preferences to see what's going on:
    My account is now "Standard" not "Administrator"? Other posts suggest Reboot from DVD/ Utilities/Change Password etc.
    2. But I can't change any settings like "Start-up Disk" or "Account Privileges" in System preferences without Administrator Name/Password.
    3. Can't find a way to reboot from DVD (Have tried "C", "Option"). Just keeps coming back to Login Screen.
    Help!!!!!!!!!!!

    I have the same problem. After installing Leopard all my accounts were changed to "Standard". So I try to boot to the CD and hold down any boot commands (c or command-s or option) and none of these work. Talked to Apple for an hour on the and they want me to take it to an Apple because there is firmware that locked.

  • Lost Admin rights

    Hi,
    The user with admin capability on my iMac running Snow Leopard 10.6.7 disappeared from the list
    of accounts in System Preferences. I'm unable to pinpoint when it happened but reckon it was the recent
    update to 10.6.7.
    Booting into single user mode it was apparent that the user existed but with uid
    and gid of 501 and membership of the nobody group only. The password was also corrupted. I have been able to
    correct this using the procedure in TS1543 and dscl commands so that the user
    is now a member of the wheel and staff groups. I am now able to login but the user no
    longer has admin capability.
    Permissions and the disk have been repaired and verified by booting from SL Install DVD. Oddly, permissions
    were not changed for ARDAgent and everytime I login with this 'recovered' user I have to re-enter the wireless router
    security details.
    I'm unable to reset any admin user passwords using the Installation DVD and the Reset Password utility because no
    admin or root user appears in the list of ids to modify.
    When I boot into single user mode and view attributes I see entries that include the group 'admin' but after running
    launchctl load /System/Library/LaunchDaemons/com.apple.DirectoryServices.plist all references to 'admin' become '80' and
    root become '0'. Run launchctl unload and the normal id and groups re-appear.
    So when I try use dscl to add my user to the admin group, it returns an error. Should I be able to manipulate group membership using '80' rather
    than 'admin' because  I can't figure out how to get that to work ? Or are there other commands I could use to change group membership ?
    I am ofcourse unable to create an admin user using the standard facilities in
    Accounts/System Preferences because all users are currently standard or managed users.
    I have seen suggestions to delete /var/db/.AppleSetupDone but on restart I just get a gray screen.
    I don't really want to splat the system and re-install apps if I can avoid it.
    Can anyone advise on the next steps ?
    Thanks in anticipation .....

  • Agent Installation on users without Admin Rights

    There are around 500 users and all are having non admin rights on their computers. When the software is download from the cas to the users pc it says that the software cannot be installaed as the user does not have admin rights. so each time we have to logon as a admin and install the software. Is there an easy way that we can install the agent. Even if i have to install the stub, it also requires admin rights.

    Talha,
    That is correct. You have to install the stub as an admin. For convenience it is available as a MSI which you can push using any of your software push methods you use (SMS, GPOs, Altiris etc) but the initial install requires admin access.

  • Want to configure a GPO "Stop (domain) users [having admin rights] from installing software"

    Want to configure a GPO "Stop (domain) users [having admin rights for some particular users]  from installing/uninstalling software"
    Requirements :-
    1. Domain user should not be allowed to install/uninstall any software's. Rest all the actions can be performed by the user like an administrator can do.
    Please suggest if possible then how can I implement the same.

    Hi Amar Chand,
    You can do so by using certain Group Policy settings to control the behavior of the Windows Installer, prevent certain programs from running or restrict via the Registry Editor. The Windows Installer, msiexec.exe, previously known as Microsoft Installer,
    is an engine for the installation, maintenance, and removal of software on modern Microsoft Windows systems.
    You can try the following method to resolve this issue:
    Method 1: Disable or restrict the use of Windows Installer via Group Policy
    Open “GPMC”, create a GPO linked to the correct scope. You can refer to this article
    Create a new Group Policy object.
    Right-click it, click Edit, and then navigate to
    Computer Configuration/Policies/Windows Components/Windows Installer.
    In RHS pane double-click on Disable windows installer.
    Click Enable and configure the option as required. "Always "option indicates that Windows Installer is disabled.
    This setting affects Windows Installer only. It does not prevent users from using other methods to install and upgrade programs.
    Click Apply to save this configuration.
    Run gpupdate /force on the clients. 
    For your information, please refer to the following article to get more help:
    Managing options for computers through Group Policy
    http://www.microsoft.com/resources/documentation/windows/xp/all/proddocs/en-us/sag_wininstall_group_policy_computers.mspx?mfr=true
    Method 2: Restrict Programs from being installed via Registry Editor
    Open Registry Editor and navigate to the following key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Policies\Explorer\DisallowRun
    Create String value with any name, like 1 and set its value to the program’s EXE file.
    e.g., If you want to restrict msiexec, then create a String value
    1 and set its value to msiexec.exe. If you want to restrict more programs, then simply create more String values with names 2, 3 and so on and set their values to the program’s exe.
    Note: You may have to restart your computer.
    In addition, if you choose this method, you could deploy the registry configuration via GPO. Please refer to the following article:
    Configure a Registry Item

  • Firefox 3.6.15 is not downloading on MAC OSX, not via software update nor via manual download. It claims i do not have full admin rights which is not true.

    If I do a manual download via FF website, it starts to install, asking if I want to replace an older version of FF. If I then continue, it says that it cannot process as I do not have access to 'certain components'????
    I have full admin rights, it is f... my computer. I am running a Macbook Pro on OSX 10.6.6.
    FF is giving me more problems lately, a.o. not showing certain flash elements (have latets flashplayer). Anyone else getting annoyed with FF?

    I eventually did an archive and install to get 10.4.7 installed on my MBP the last time around. Now 10.4.8 is doing the same thing. Neither via Software Update nor manual downloads of Intel delta or combo updaters will apply. Arg!
    Has anyone else seeen this? I've tried applying the update while booted regularly and also in safe boot to no avail.

  • ZEN Agent install without admin rights

    Hi all,
    Sorry to re-visit something I've seen a number of posts on, but I can't
    seem to get things to work as I've been lead to believe they should. We
    have a handful of systems that do not have any instance of the ZEN agent
    installed, a mix of NT and XP (odd, I know). We are attempting to create
    an automated process that will establish whether the agent is on the
    system and if it is not, install it. Seems pretty straight forward and
    I've been referencing the following suggestions. There are a number of
    posts in the forums as well, but these were the most relevant.
    http://www.novell.com/coolsolutions/trench/3490.html
    http://support.novell.com/cgi-bin/se...?/10085696.htm
    http://www.novell.com/coolsolutions/trench/3383.html
    http://support.novell.com/cgi-bin/se...?/10073212.htm
    The problem is, despite what these instructions say, we cannot install the
    agent without having local admin rights. All the batch files are in
    place, and work, but ultimately the install fails. I've seen work arounds
    for any OS later than NT, but its important that every system have the
    agent.
    I've tried almost everything suggested in the links above but I am
    primarily pursuing the batch file approach as detailed in...
    http://support.novell.com/cgi-bin/se...?/10085696.htm
    At what point are rights elevated such that the install can complete in an
    NT environment?
    I am sure I'm forgetting some relevant details, so humor me please.
    Thanks in advance.
    Mike

    I forgot that RunAs does not come with NT. ( It's available as an add-on,
    but even that needs admin rights to install.)
    Try PSExec from http://www.sysinternals.com, but I believe that will not
    work either, but worth a shot.
    Another outside shot is to push the "AlwaysInstallElevated" MSI installer
    registry keys via a batch file.
    Unfortunately, I doubt your logged on user has the rights to do this
    either..............
    You may be stuck manually visiting and installing manually.

  • Installing without admin rights on Win7

    I am trying to get a definitive answer to whether Adobe Creative Cloud can be installed and used by someone who does not have administrator rights to their Windows 7 PC. In our company, we restrict user rights and users cannot "elevate" their rights to install software. Normally, we package ALL software and deploy it by Microsoft SCCM, which overcomes any admin problems automatically. We could presumably do that to install the initial cloud download manager application. But it is not clear whether that will then be able to install the specific applications the user requires when logged in using their (user mode) account. Does the creative cloud installer run as a background service - that could be set to run with an administrator service account? Can one user with access to the cloud downloa da traditional installer package which could then e passed to SCCM for deployment to other colleagues? Is there any official suggestion from Adobe how companies that enforce lock-down of user rights can use the Cloud?
    Thanks!
    Anthony

    Hi Anthony,
    I know that installation at least requires admin rights and most likely first launch with some of the apps. I believe its possible to run most of the apps from a limited user once installed. This is true for all Adobe products not just Cloud products. I believe we are working on options for deployment for Creative Cloud Team which would support technologies such as SCCM, so even if this option is not available for cloud currently, it may be something that is available in the future.

  • Folio Builder panel in CS6 and CC (says update required) - can't install update (no Admin rights)

    Hi. I've been running CS6 and the Folio Builder Panel keeps saying "DPS — A software update is required, go to the Help menu for Updates..." When I go to the Help section there are no updates. I recently moved to CC hoping the problem would fix itself but it hasn't. I downloaded the DPS Package update for both versions of the program — and I tried to install each one. Both give me error messages saying I don't have Admin rights. Adobe's tech support walked me through enabling Admin rights (although I should have had them already) and that didn't work.
    Has anyone else had trouble installing the DPS update? I would like to actually use the DPS tools!
    Thanks

    Hi Bob, I ended up having to uninstall CS6, then reinstall it — then for a separate Folio Builder log in issue, I followed another thread and removed the (Application Support/Adobe) OOBE folder. Functioning smoothly for now! Thanks for your suggestion.

  • Install applet without admin rights

    Hi,
    Apologies for my complete lack of knowledge here, but I'm wondering if there's a way of installing java applets on users profiles who don't have local admin rights on their machine.
    Basically, I work for a company with a lot of users who access various websites with java applets. However, each time a user requires access to one of these sites, we have to grant them local admin rights, open the site to install the applet, then remove the rights again. I was hoping there might be a better solution to this?
    Any suggestions would be greatly appreciated.
    Cheers
    Andy

    Bad news I am afraid.
    Apple properly implement UAC (User Access Control) whereby whenever something tries to install itself it does ask for an admin level authentication. Microsoft's effort in this area ***** big time even if in other areas they may be better than Apple.
    Therefore as things stand you need it to be authenticated by an admin level password.
    Now looking forwards there are two possible approaches which would make both your IT department happy and let you work.
    If your IT department sets up a system whereby they can remotely control your computer they can remotely authorise the installation. This is an absolute pig to do with Windows machines as in Windows normally the authorisation dialog kills the remote control session but thankfully it is easy with Macs. This may require having a VPN connection to the office but some remote control systems do not need this e.g. LogMeIn
    or they could set up a 'self-service' software install system like Munki. There would be a server with the installers on it including the XCode installer and your Mac would be configured to talk to this, you Mac would have the Munki Managed Software client on it and this client would manage installing the applications and would also manage the authorisation for you meaning you would not need to enter a password
    Even once you have XCode installed it is my experience that using it to develop software usually requires admin access anyway, the development company I worked at in support therefore conceded the inevitable and gave all the devs admin level accounts with the understanding that if they broke things they had to fix it themselves.
