    I am sorry but Acrobat 7 is not at all compatible with Windows 8. For this, you will need to upgrade your Adobe Acrobat version.

    I can't download the Adobe Premiere Elements 13. Akamai Download pop up only the download window but downloading do not start. Alternate download Method will start but downloading will stopped always after 655 Megabytes. I have tried with different browsers, fire wall and virus protection off and also to download the trial of Adobe Premiere Elements 13 but result is every time same.

    if you follow all 7 steps you can directly download a trial here:  http://prodesigntools.com/photoshop-elements-13-direct-download-links-premiere.html
    and activate with your serial number.
    if you have a problem starting the download, you didn't follow all 7 steps, or your browser does not accept cookies. 
    the most common problem is caused by failing to meticulously follow steps 1,2 and/or 3 (which adds a cookie to your system enabling you to download the correct version from adobe.com). 
    failure to obtain that cookie results in an error page being displayed after clicking a link on prodesigntools.com or initiates the download of an incorrect (eg, current) version.

  • SFC problem - "Windows Resource Protection could not start the repair service"

    We are trying to attempt to fix a Windows 2008 start up problem. We boot the machine from a Windows 2008 CD and go to the repair tool - command prompt.
    When we do the command sfc /scannow, we are getting
    "Windows Resource Protection could not start the repair service"
    We did some researches there someone suggested the trustedinstaller is not running so we tried to do a net start trustedinstaller.
    But We are getting
    "The windows modulers instaler service is starting
    The windows modulers instaler service is starting could not be started
    A system error has occured
    System error 1067 has occured
    The process terminated unexpectedly. "
    Anyone can give us an idea to see why we can not run the sfc the first place. Thanks

    SYMPTOMS:
    All attempts to run command:
    sfc /SCANNOW
    keep returning the following message:
    "Windows Resource Protection could not start the repair service"
    SOLUTION:
    If you are using any kind of boot image/disk to boot up, you will have to use the "offline" switches (OFFBOOTDIR & OFFWINDIR) along with the SFC /SCANNOW command in order to start repairing your instalation properly.
    please remember to tripple-check for corret partition letters, because this is a crucial parameter for SFC to start working properly.
    also make sure to confirm whether so called "recovery" partion exists in your specific scenario or not. If so, in most cases this will render the "recovery" partition being the one to be set as a boot partition (OFFBOOTDIR) within sfc command, while Windows
    system folder (OFFWINDIR) will actually reside on a different partition.
    My scenario is described exactly above and therefore in my case boot partition letter was C: and system partition was D: ...As of that - the proper command line to run SFC successfuly was:
    sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\Windows
    Successful scan for integrity of all protected system files and replacement of incorrect versions with correct Microsoft versions then looks like this:
    X:\sources>sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=d:\WindowsBeginning system scan. This process will take some time.Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.logwindir\Logs\CBS\CBS.log. For example C:\Windows\Logs\CBS\CBS.log
    Once SFC scan completed, I have run the Startup Repair from the repair dialogue menu prior rebooting the system. Remember to click "Cancel" on the prompt for using the System restore in this step. I am assuming you have tried this already time ago and confrmed
    it did not resolve the problem, but most importantly - you really would not want to overwrite the files, which you have just repaired with any possibly corrupted ones ;)
    After this I've unplugged bootable USB key with the My Windows Vista Enterprise 64bit setup disk image and restarted computer. System booted up properly on first attempt. No issues have been identified as a result of my post boot checks. This completely
    resolved the issue in my case. Should you have questions, please let me know.

    I've also got a similar problem. I upgraded yesterday & today I find (mainly with previously purchased tracks) that iTunes only playes about 51sec of a track. The whole track plays when using "Quicktime" but this doesn't help me when I'm trying to put together a playlist.

  • Windows Deployment Services will not start

    After advertising a image to my remote client computer I receive this error:
    PXE-T01: the specified file was not found
    PXE-E3B: TFTP error - file not found
    PXE-M0F: Exiting Broadcom PXE ROM
    I logged into the server and noticed the "windows deployment service" is not running. I tried to start the service and it failed to start. I then checked the "Site System Status" log and noticed there was a "Critical" message for the PXE service point role,
    and a "warning" message for the management point role.
    On 8/16/10 for the PXE service point role I see this critical error: PXE Control Manager detected PXE service point is not responding to pxe requests. The error is 16389. Possible cause: pxe service point is not started or not responding.
    I would greatly appreciate any assistance.
    Thank you

    Thank you everyone for your patience and assistance. I have resolved the issue after double, and tripple checking everything. The problem was that the boot images (x64, and x86) were not pointed to SMSPXEIMAGES$ distribution which is the server share. I
    pointed it to the Server only. After pointing to both the share, and the server all works fine.
    So the initial issue with the deployment service not starting was to uninstall WDS, and the PXE option in SCCM. During the troubleshooting I accidently deleted the SMSPXEIMAGES$ distribution point from the boot image which caused another issue after resolving
    the windows deployment problem.
    Hope this helps the next person that has this issue.
    The solution exists already in the link that I gave you, see the point N°5 :)

  • Windows listener service will not start automatically

    I just installed 11.2.0.3 Standard Edition One and when I reboot the server, the listener service is not started. The service is set to start Automatically. I have to login, open services and then push start.
    The oraceServiceSId does start automatically,
    The listerner service does not start automatically,
    The dbconsole service does not start automatically,
    The processManger1 service (from middleware) does not start automatically
    This is Windows 7 64 bit.
    Any ideas?

    I found where the services logs are recorded in the event viewer. Funny thing just happened, I was just about to do another reboot so I could check the logs when I noticed there were window updates in q.
    So after running the updates, the os requested to reboot . For the first time, the services started automatically.
    These are the updates which fixes the probem:
    Security Update for Windows 7 for x64-based Systems (KB2639417)
    Cumulative Security Update for Internet Explorer 9 for Windows 7 for x64-based Systems (KB2618444)

  • Windows listener +service does not start automatically eventhough Automatic

    So now we have to manually restart the listener and service , for the database to be opened. Is it possible to give direction what areas need to check, to solve this issue?
    Thanks.

    Hi Krithi,
    Can you confirm my understanding here:
    * Since a short time the automatic startup of the listener and Oracle instance fail.
    * You can manually startup the listener and database instance without any problem, and then all runs as expected
    so far so good?
    What's your procedure to start the listener and DB instances?
    Are you performing the startups with your own user account, or SYSTEM, or a dedicated Oracle account?
    Are the windows services running under SYSTEM, a dedicated Oracle user....??
    Could it be that the system administrator installed something (like a new Oracle client) which would have changed some settings?
    Can you compare the environment variables (ORACLE_HOME, ORACLE_SID, PATH) between the account YOU use for manual startup and those for the user account used to (auto)start the services?
    Maybe you can try to plan a reboot after you have set the problematic services to run under your profile?
    Well.... a few points to investigate if not yet considered.
    HTH,
    Thierry

  • Windows Audio Services will not start

    The sound on my HP Presario stopped working. Diagnostics said it was because the Windows Audio Services was not running. When I go to the Microsoft Management Console and try to start it again, I get Error 1068 - The dependency group failed to start. Any suggestions?
    Presario SR 5000
    Vista Home Premium

    Hi Mziggi,
    You may want to try installing the latest audio driver for your PC directly from the original device manufacturer. I'm not sure what your exact model number is (SR5000) is the series, but of the SR5000's that I've looked up they tend to have the Realtek High Definition Audio. If this is true for your PC (and I think it is), here is a link to the Realtek download site:
    http://152.104.125.41/downloads/
    Just select "High Definition Audio Codecs", select the agreement, and then download and install the driver for your operating system.
    I hope this helps. Let us know how it goes.

  • Installation of TREX 7.0 on 64bit windows then SAP does not start

    I have implemented EP7 Portal (NW04s SP11) on a MS-SQL DB with windows 2003 64bit hardware.  I also want to install TREX which is version 7.0 on the same server.
    After installing TREX the http_server would not start. I followed OSS note 1008299 that instructed me to set IIS to run in 32 bit mode as TREX 7.0 really isn't a 64 bit application!!
    I performed this but now the service for my SAP Java instance will not start:
    error : "The dynamic link library librfc32.dll could not be loaded"  (SCS does start OK)
    Its obviously got something to do what I've just performed...
    any help anybody?
    thanks
    SB.

    Hi Simon,
    Actually trex was not released for a 64 bit component. But in the installation CD, it was printed mistakenly.
    For that only, SAP has given note 1008299 to run IIS in 32 bit mode instead of 64 bit mode, because although you have done the installation as a 64 bit machine, its for 32 bit platform only.
    Running the script will start your IIS on a 32 bit mode and also, change your executables, file folder as well.
    Previously, i also had the same problem and once i did as per the note, its working perfectly now.
    Thanks and Regards,

    Hey there
    Well Microsoft patch kb2677070 automatically updates revoked security certificates. It lets  Windows Server go out to the internet. But if your server is firewalled away in a DMZ and does not have unfettered internet access, this call to the find the updated
    revocation list will fail. When it does, the SharePoint 2010 Administration service will not start.
    Open Group Policy Editor. From start->search box, type in gpedit.msc and hit return.
    Navigate to Computer Configuration->Windows Settings->Public Key Policies-> Certificate Path Validation Settings.
    Click on the “Network Retrieval” tab.
    Check the “Define these policy settings” and uncheck the “Automatically update certificates in the Microsoft Root Certificate Program”
    Click OK

  • Windows Zero Configuration does not start automatically

    It won't start automatically, even though I have set it to automatic in the Services Tab. Every time the computer goes to sleep, logs out or restarts, I have to go back into Services and restart it. How can I get it to start automatically. NOTE: I HAVE CHANGED THE STARTUP TYPE IN THE SERVICES TAB BUT IT IS TO NO AVAIL (I have asked this question in other places, and they still give me this answer, so I hope you guys are smart enough to not tell me what I already said I did.)

    On the recovery tab of the service properties, set them all to restart.  Does that work for you?  If you can not start a service, there might be some kind of malware or virus that is forcing the service to start.  Could also be a corrupted file on the hard drive.  If you look at your event logs, does it show what any error messages?

  • Itunes 10.3 on Windows 7 64-bit not starting up

    Itunes has always been working fine on my pc up until one day, I click on the Itunes icon, and it looks like it's loading for like 3 seconds and then it does absolutely nothing...
    I tried re-installing the program twice, nothing.
    I tried opening MsConfig and disabling all applications upon start up except for Itunes and Quicktime (which I believe was a suggestion here on this website for this problem). But that did nothing...
    Not to mention I re-booted the computer countless times... And that did nothing...
    I don't really think giving out my computer performance specs really matters, only that I am running Windows 7 Home Premium 64-bit. The version of iTunes I have is the latest version 10.3 (64-bit) for Windows.
    Can somebody please tell me what is going on and how to get my iTunes working again? I would highly appreciate it!! Thank you in advance!

    Many thanks.
    That's consistent with an application (other than QuickTime itself) having dropped old QuickTime componentry in your system files.
    So just in case we'll go looking for older QuickTime componentry in the most common locations for it to be stashed.
    First we'll need to change some view settings.
    In your Start menu, open Computer.
    In your Organise menu, select Folder Options.
    In the View tab, make sure that "Show hidden files and folders" is selected, and Hide extensions for known file types is unchecked.
    Click OK.
    Now in Computer, open your C:\ drive (or whichever drive you have your operating system installed on).
    Open the "Windows" folder.
    If you have a 32-bit version of Windows, open the "System32" folder.
    If you have a 64-bit version of Windows, open the "SysWOW64" folder.
    What files and folders can you see in there with QuickTime in the title? (In a standard installation of Quicktime you should be seeing precisely two files... QuickTime.qts and QuickTimeVR.qtx ... and no QuickTime folders whatsoever.)
