"Data Execution Prevention" prevents Reader 9.0 & 9.1 from running

Jul 30, 2009 11:12 AM

When I try running Adobe Reader 9.0 or 9.1, the Windos "Data Execution Prevention" feature prevents it from running. I just received a new DELL computer with Vista Home Premium OS with Adobe 9.0 already installed. When I run the Adobe Reader, it stops executing because it is using a part of memory reserved for system files. Windows states that "Data Execution Prevention" has stopped the program to prevent possible corruption. I downloaded version 9.1 and still have the same problem. I downloaded the "light" version of Version 9.1 and still have the same problem. If I try running from Firefox or from the Desktop icon, I still have the same problem. When I try from the Control Panel to set Data Execution Prevention to exempt Adobe Reader, I get a message that Adobe Reader needs to run under DEP and cannot be exempted. So, I can't run Adober Reader 9.1 becasue Windows "Data Execution Prevention" stops it. Can anyone help? Thanks.

    I have a user experiencing the same problem.  Opening the program itself (not by executing a pdf file) end up crashing Adobe immediately.  Initiating Adobe Reader from a PDF file, it appears to crash during "Initializing DigSig(2).api".  As other users have noted in other threads pertaining to this problem, Data Execution Prevention pops up a message basically telling the user that the program was blocked and to make an exception.  When I try to do this for AcroRd32.exe, DEP complains that the program must run with DEP enabled and it cannot be turned off for this program. I've installed Foxit Reader as a temporary work-around, but we have a lot of industry-specific programs that rely heavily on Acrobat Reader and I fear it may have a much more far-reaching problem since Adobe Acrobat Reader 9 is dead-in-the-water.  Anyone have any thoughts on this?  Is Adobe/MS working on a solution?


    Windows Vista Home Premium SP2 64-bit

    Internet Explorer 7

    Acrobat Reader


    I've tried uninstalling, then reinstalling as normal and no joy.  I downloaded the "lite" and stand-alone installer from the ftp site, still crashes Reader.  The error as reported by the Event Viewer:

    I am having the same problem with Acrobat Reader X.


    I am using Adobe Reader X and am constantly getting a Windows "data execution prevention" error every time I open and close a pdf file. What can I do to resolve this as Windows says it can not shut off "data execution prevention" for Adobe reader?
