When I try to install Adobe Acrobat Reader 9 I get the message "The system can not open the device or file specified" from Windows Installer. It happens when the AcroRead.msi file executes. I looked all over the Adobe Knowledge Base, couldn't find anything. I looked on Microsoft's Knowledge Base, it mentioned something about the TEMP folder being encrypted, which it isn't ... I tried getting rid of the Adobe keys in the Registry... didn't help. When I tried to reinstall Acrobat Reader 8.1 the same thing happened. I even tried downloading a new version of Microsoft Installer ... no help. Does anyone have any idea what it's referring to ? ? ? ? ? ? ?
