Acrobat X - Win7 Problem: Access denied

Dec 3, 2010 2:45 AM



since the new version X our plugin doesn't work anymore when using it with Win7. WinXP still works fine with version 10.X and version 9.X works fine with all OSs. We are using the following method:




and on Win7 systems an errorcode "Access Denied" is returned.

Anybody any idea? Any known bug?

    Since there is obviously something specific in the param block that is causing this you need to open a formal support case

    At this time, we have not yet posted an SDK for Acrobat X.  So 9.1 is current.

    No there is not.


    However, if we do determine it to be our bug, then we will refund the $$.

    Thanks ToM_1st-   exactly the solution for my problem.  I followed the steps in


    1. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Adobe\Acrobat Reader\10.0\FeatureLockDown.

    2. Right click and choose

    New > DWORD Value

    3. Create   bUseWhitelistConfigFile.

    4. Right click on bUseWhitelistConfigFile and choose Modify

    5. Set the value to 1 to enable the white list.


    then make a file-



    with one policy Whitelist line

    ; Files Section
    FILES_ALLOW_ANY = c:\*


    then save that file in-

    C:\Program Files (x86)\Adobe\Reader 10.0\Reader


    what a major pain.  i guess someday i will sit down and read the manual.  Warning,  i am sure i have exposed myself to something bad with the c:\*  !   maybe create a particular folder to quarantine/isolate incoming PDFs for security purposes.


    of course in Win7 had to switch to be an admin user to do this.  Then I couldn't even read the AppSecurity manual i had just downloaded.
