    Vista SP2 VSE 8.5i upgrade to VSE 8.7i Repost 4 disabled VBScript

      VBScript was working normally before the upgrade, and ever since the install of 8.7i with Patch 4 repost (3 days ago), VBScript is failing.  I have tried to re-register the vbscript.dll which succeeds without an error, but I still get the error message "Can't find script engine ""VBScript for script ...".  I currently have VSE 8.7i Patch 4 with DAT 6232 Engine 5400,   VSE is un-managed, and computer is Vista Ultimate SP2 x86 stand alone (no domain).  Manually disabling all of VSE - Access Protection, Buffer Overflow, Email, On-Access still does not fix the issue.  I did find a very old article about VSE 8.0 requiring patch 13 or higher to fix the behavior that VSE would not respect the disabling of script scanning, but I doubt this applies (I don't remember if I ever had VSE 8.0 installed, I doubt it worked with Vista anyways).

          The script scanning included with VirusScan enterprise modified this registry key

           

          [HKEY_CLASSES_ROOT\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32]
          @="C:\\Program Files\\McAfee\\VirusScan Enterprise\\scriptcl.dll"
          "ThreadingModel"="Both"

           

          which caused VBScript to fail.  A complete uninstall of VSE 8.7i Repost 4 left this key unmodified, causing VBScipt to fail since this McAfee dll no longer exists.  Manually changing the registry key to the windows default:

           

          [HKEY_CLASSES_ROOT\CLSID\{B54F3741-5B07-11cf-A4B0-00AA004A55E8}\InprocServer32]
          @="C:\\Windows\\System32\\vbscript.dll"
          "ThreadingModel"="Both"

           

          solved the issue.  I am now going to attempt a clean install (not looking forward to verifying steps in KB59996), then uninstall to see if the problem reoccurs, or if this was only caused by the VSE 8.5i - 8.7i Repost 4 upgrade I performed.

           

          For others with the same problem you might attempt the steps in https://kc.mcafee.com/corporate/index?page=content&id=KB52222 , it's possible that unregistering the ScriptCl.dll might fix the registry key.  Step 11 in KB50602 How to manually remove VirusScan Enterprise 8.5i  also states to unregister this DLL.
