Hi...I have a Windows 8.1 Dell laptop I recently acquired. I cannot install the Google Voice & Video plugin for my Gmail via Comodo Dragon(ie Chromium.) I had it installed and it was working...then all of a sudden it stopped so I attempted numerous times to re-install it. According to information on the Internet it may have something to do with corrupt Windows Installer files so I ran the "scannow" feature and it stated that there were corrupted files Windows couldn't fix. I don't understand how that even happened since I've only had this computer a few months...purchased new from Dell. Anyway I also attempted to unregister and reregister the Windows installer file but that also didn't work. I went to try the MS fix-it however it isn't supported by 8.1 and so is greyed out...cannot even run that in backwards compatibility mode. I've scoured the internet but haven't found anything. Any advice on this matter would be greatly appreciated...
