    "Unspecified Error" or "Runtime Error" 7 when launching application with AcroPDF on Secured Vista PC.

      We have a client application written in Visual Basic 6 that uses the AcroPDF ActiveX DLL to view PDF files in our app.  The app works fine the clients secured Windows XP SP 3 PC, and on my Windows Vista Business 32 bit Virtual Machine.  However, the application will not launch on the client's highly secured Vista Enterprise 32 bit PC's.  The form with the Acrobat Browser control does not even initialize before a "Runtime Error 7: Out of Memory" message is presented.  I created a VB 6 test app that has just the form and the Acrobat Browser control on it, and this test application will not initialize either.  It gets an "System Error &H80004005 (-2147467259). Unspecified Error" message on attempting to launch.  I get the same error message if I attempt to add the Acrobat Browser control to a form in an MS Excel Macro in Excel 2003 on the same PC.  Test VB6 applications using the other controls and references in the application launch fine.

       

      The Acrobat installed on these PC's is Acrobat Professional 9.0.0 and/or 9.1.0.  In two cases, we have been able to have the application load after uninstalling /reinstalling Acrobat 9.x on the PC, but ONLY for the profile that did the installation.  And in one case, after removing that user profile and then logging back on, that user started getting the same errors above.

       

      What policy or registry setting is needed to get this control to initialize on a secured Vista PC for all users?
