"Safari can't install this extension" error on ALL extensions

I get this error on every single Safari extension I've tried. For example the Twitter extension on this page: http://extensions.apple.com/. I'm on Safari 5.1 on Mac OS Lion 10.7.1. I've experienced this problem ever since upgrading to Safari 5 back on Mac OS 10.6.

Yes - I created a new user account and I tested Safari - everything worked as it should. Problem solved so I then ported over all the existing data to the new user account. Give that a try...

  • Can't install safari extensions, I get the error message "Safari can't install this extension, An error occurred while installing the extension "Pin It Button"." Any suggestions?

    Every time I try and install an extension for Safari I get the error message "Safari can’t install this extension, An error occurred while installing the extension “Pin It Button”." I have all the latest updates, working on OS X Yosemite v 10.10.2 / Safari v 8.0.3. Any suggestions?

    Back up all data before proceeding.
    Launch the Keychain Access application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    Use the search box in the toolbar of the Keychain Access window to search for an item named "Safari Extensions List". If found, delete it. Quit Keychain Access.
    Quit and relaunch Safari.

  • Safari can't install this extension...

    After the last up-dates Safari extensions broke. Now unable to reinstall all extensions.
    Have been able to work around this in the past but nothing I did before works now.
    "Safari can’t install this extension" An error occurred while installing the extension...
    OSX 10.10.3, Safari 8.0.5 (10600.5.17)
    Thanks All

    Back up all data before proceeding.
    This procedure will unlock all your user files (not system files) and reset their ownership, permissions, and access controls to the default. If you've intentionally set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it, but you do need to follow the instructions below.
    Step 1
    If you have more than one user, and the one in question is not an administrator, then go to Step 2.
    Triple-click anywhere in the following line on this page to select it:
    sudo find ~ $TMPDIR.. -exec chflags -h nouchg,nouappnd,noschg,nosappnd {} + -exec chown -h $UID {} + -exec chmod +rw {} + -exec chmod -h -N {} + -type d -exec chmod -h +x {} + 2>&-
    Copy the selected text to the Clipboard by pressing the key combination command-C.
    Launch the built-in Terminal application in any of the following ways:
    ☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
    ☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
    ☞ Open LaunchPad and start typing the name.
    Paste into the Terminal window by pressing command-V. I've tested these instructions only with the Safari web browser. If you use another browser, you may have to press the return key after pasting.
    You'll be prompted for your login password, which won't be displayed when you type it. Type carefully and then press return. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
    The command may take several minutes to run, depending on how many files you have. Wait for a new line ending in a dollar sign ($) to appear, then quit Terminal.
    Step 2 (optional)
    Take this step only if you have trouble with Step 1, if you prefer not to take it, or if it doesn't solve the problem.
    Start up in Recovery mode. When the OS X Utilities screen appears, select
              Utilities ▹ Terminal
    from the menu bar. A Terminal window will open. In that window, type this:
    resetp
    Press the tab key. The partial command you typed will automatically be completed to this:
    resetpassword
    Press return. A Reset Password window will open. You’re not going to reset a password.
    Select your startup volume ("Macintosh HD," unless you gave it a different name) if not already selected.
    Select your username from the menu labeled Select the user account if not already selected.
    Under Reset Home Directory Permissions and ACLs, click the Reset button.
    Select
               ▹ Restart
    from the menu bar.

  • Safari can't install this extension because Extensions are disabled. Extensions can be enabled in Safari's Extensions preferences.

    i have this problem. Anyone can help me?

    Ok...
    Open a Finder window. Select your Home folder in the Sidebar on the left.
    Now open the LIbrary folder then the Safari folder then the Extensions folder.
    Move the Extensions.plist file from the Extensions folder to the Trash.
    Restart your Mac.
    See if that helped.

  • Safari won't start after showing an error message: Safari can't use the extension "Omnibar" because the extension is no longer valid.

    Since yesterday evening (19-01-2015) safari won't start. After clicking the safari application it shows an error message: Safari can't use the extension "Omnibar" because the extension is no longer valid.
    This message almost directly disappears whereupon the Problem Report opens. I've tried to find a solution on the web but without succes.
    I'm running OS X Yosemite version 10.10.1 and Safari version 8.0.2 on a:
    MacBook Pro (Retina 13-inch, Mid 2014)
    Processor 3 GHz Intel Core i7
    Memory 16 GB 1600 MHz DDR3
    Graphics Intel Iris 1536 MB
    Since I updated to Yosemite I've been having multiple problems. I already read a clean install will solve most of them. But till then I would love safari to work again.
    Thanks!

    There is no need to download anything to solve this problem.
    If Safari crashes on launch and you don't have another web browser, you should be able to launch Safari by starting up in safe mode.
    You may have installed the "Genieo" or "InstallMac" ad-injection malware. Follow the instructions on this Apple Support page to remove it.
    Back up all data before making any changes.
    Besides the files listed in the linked support article, you may also need to remove this file in the same way:
    ~/Library/LaunchAgents/com.genieo.completer.ltvbit.plist
    If there are other items with a name that includes "Genieo" or "genieo" alongside any of those you find, remove them as well.
    One of the steps in the article is to remove malicious Safari extensions. Do the equivalent in the Chrome and Firefox browsers, if you use either of those.
    After removing the malware, remember to reset your home page in all the web browsers affected, if it was changed.
    If you don't find any of the files or extensions listed, or if removing them doesn't stop the ad injection, then you may have one of the other kinds of adware covered by the support article. Follow the rest of the instructions in the article.
    Make sure you don't repeat the mistake that led you to install the malware. Chances are you got it from an Internet cesspit such as "Softonic" or "CNET Download." Never visit either of those sites again. You might also have downloaded it from an ad in a page on some other site. The ad would probably have included a large green button labeled "Download" or "Download Now" in white letters. The button is designed to confuse people who intend to download something else on the same page. If you ever download a file that isn't obviously what you expected, delete it immediately.
    In the Security & Privacy pane of System Preferences, select the General tab. The radio button marked Anywhere  should not be selected. If it is, click the lock icon to unlock the settings, then select one of the other buttons. After that, don't ignore a warning that you are about to run or install an application from an unknown developer.
    Still in System Preferences, open the App Store or Software Update pane and check the box marked
              Install system data files and security updates (OS X 10.10 or later)
    or
              Download updates automatically (OS X 10.9 or earlier)
    if it's not already checked.

    If your serial number is listed as being valid at http://www.adobe.com/ then I would recommend obtaining a fresh copy of the installation files.  You can find details on how to locate your serial number at Find your serial number quickly - http://helpx.adobe.com/x-productkb/global/find-serial-number.html.

    Photoshop CC

    Hi,
    Have you ever uninstalled Photoshop CC and installed Photoshop CC 2014, or uninstalled Photoshop CC 2014 then installed Photoshop CC?
    If that, please re-install you uninstalled Photoshop, and remove GuideGuide from Extension Manager before uninstall.
    Another option is remove extension manager database file, then launch Extension Manager to install it.
    C:\ProgramData\Adobe\Extension Manager CC\Configuration\DB\ExMan.db (Windows)
    /Library/Application Support/Adobe/Extension Manager CC/Configuration/DB/ExMan.db (MAC)
    But please notice that all your previously installed extensions will not be shown in Extension Manager after you removed database file.

  • How can I install an extension when it conflicts with an existing one that doesn't appear in the list of extensions?

    I'm trying to install Guide Guide for Photoshop CS 2014 using the Adobe Extension Manager CC but when clicking on the 3.1.2-guideguide.zxp I recieve the following error, "This extension cannot be installed, since it conflicts with a existing one. To install this extension, please remove the extension 'GuideGuide' which has been installed in ", then install again."  Note that there is some code breaking in there where ", is.  When I open Adobe Extension Manager CC there are no extensions listed.  None under any of the products to the left.  I can't uninstall it if it's not listed.
    After reviewing the forums I have gone into my %appdata%\Roaming\Adobe\ folder and removed all folders for previous versions of Adobe Extension Manager.
    Any help with this issue would be appreciated.  Thank you for your time.

    Please delete "C:\ProgramData\Adobe\Extension Manager CC\Configuration\DB\ExMan.db" then retry. Note that "C:\ProgramData" is hidden by default. You can input C:\ProgramData in the address bar of Windows Explorer then press "Enter" key to go into this folder.

  • Can't Install 11g Db, Error ORA 28547/24324/01041

    hi,
    I was trying to install db 11g and the installation stopped half way through with 3 errors.
    1.ORA 24324: SERVICE HANDLE NOT IDENTIFIED
    2.ORA 01041: INTERNAL ERROR, HOSTDEF EXTERIOR DOES'NT EXIST
    3.ORA 28547: CONNECTION TO SERVER FAILED, PROABLY NET ADMIN ERROR.
    I have just trained on oracle application developper and very new to installing a personal database.
    My machine is a pentium duo core 1.7, 2gb ram and 120 hdd and my OS is XP professional sp2. I connect through this machine
    through my office lan to oracle 9i db in my company server.
    I have tried to set up a 11i DB Personal and 10g developer suite on the same machine.
    I could figured out the 1st error ORA-01041 and understand that the Environment variables have to be changed before I try to
    reinstall 11g.
    As I checked up the variable from System>advanced>environment variables it is showing a very long string which is
    (C:\app\ravid\product\11.1.0\db_1\bin;%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program
    Files\Intel\Wireless\Bin\;C:\ORANT\BIN;)
    After looking this up in the c:\oracle folder trace the string only uptil 'bin'.
    I have DEVELOPER 2000 NT with Forms runtime and Graphics runtime already on the machine however i did not see any path in the
    system environment variable for this, or could it be that the string i mentioned above has that included too..one thing i know for
    sure is there was no oracle home before i tried to install the 11g db.
    Could someone also help me out with the 1st and 3rd errors as i don't know what they mean?
    Will really appreciate if you can help me through this.
    Thanks in advance for your time and advice.

  • The Safari Can't Find The Server - Error!

    After updating my iPad and Mac OSX to the latest version, I am constantly getting 'The Safari Can't find the server' error on valid addresses. I have to refresh a few times to access the website.
    I have gone through many posts and I gathere that it is not a Mac issue, but something to do with network settings - DHCP/Proxy. But I still could not figure out how to solve the problem.
    If someone can guide/advise me then that would be a great help..
    Thanks

    I'm having similar issues with Safari saying it can not find the server.  Tumblr and Zooniverse sites are particularly troublesome, even with refreshing.  I have checked the status of their servers and they are up and running without issues.  I can access them eventually but have to close the current tab and reopen later.  However, when I use Chrome or Firefox I can access the sites with no problem.  It's not a local network problem as I can access the internet and those sites on my iPhone and all other sites.  It appears to be an issue with Safai.
