I have downloaded Adobe Acrobat XI for Windows using our university's download system (so I know it's safe and authorized copy). When I double-click the .exe file to begin extraction/installation, it automatically uses WinRAR Self-Extracting Archive. I get a pop-up error "Windows cannot find "C:\Users\UserName\AppData\Local\Temp\RarSFX0\Adobe Acrobat XI\setup.exe." I cannot open/run the file using any other extractor.
I have run Malwarebytes, AVG scan and Spybot - all 3 have turned up nothing infected. I uninstalled all Adobe Acrobat, Reader, and Flash Player files. I have searched for hours and nothing I can find matches this error. Any ideas or solutions are appreciated!
