I did a clean install to Windows 7 32-bit on a Lenovo 3000 C200. Everything has been going fine (save some expected slowness). I had Adobe Air installed and running fine, was using it to run TweetDeck. I went to open Tweetdeck today and got an error message on my applications bar. Installer: Adobe AIRInstaller.exe corrupt file. It says that the macromedia/flashplayer file on C:/users/myname is corrupt, and to run chkdsk. I first tried reinstalling Air, but got an error message that it was already on the hard drive. I then uninstalled Air and Flashplayer from the control panel, reinstalled flash player with no problem, but got the corrupt file message when I tried to install Air. I then used the Flashplayer Uninstaller from Adobe to remove the Flashplayer, reinstalled again, but got the same error message for Air. I ran chkdsk and it started to scan, then suddenly disappeared. I have McAfee and Spyware Doctor, and I haven't been on dangerous websites, so I don't think I have a virus- this is the first symptom if I do. Help? TweetDeck is very helpful for my job so I would like to get it back.
