ActiveX DLL files keep disappearing

[adiomixr]

Shortly after deploying Reader 11.0.07, we discovered that the ActiveX DLL files in the Program Files\Common Files\Adobe\Acrobat\ActiveX folder keep disappearing sometime after Reader is installed, which prevents our users from viewing PDF's when selected in Internet Explorer.  The users' are prompted to save the document instead.  The DLL's seem to disappear within hours or one day.  Each time, we re-install, and again find the files missing again within a day.  This happens with 11.0.08 as well.  We have not seen this when installing 11.0.06.  Anyone else experience this?

This sounds like you either have a Global Policy that forbids those files or an antivirus software that does not have these files setup as exceptions.  Adobe Acrobat and Adobe Reader don't do this on their own and don't do this without running the Windows Installer.

I have thoroughly checked whether the files were removed by antivirus and determined that is not the case.  We also do not have a policy to block any DLL files and there are plenty of other ActiveX plugins that are working fine, that also use DLL's.  Again, we are not seeing this with 11.0.06, just 11.0.07 and newer.

How are you installing?  Are you using a customized installer?  Are you using an AIP install? Are you using a command line?  Are you using a bootstrapper?
