Windows 7 Beta: Uninstalling Adobe Air

Recently, I was trying to upgrade Twhirl, my favorite Twitter client, to the latest beta version. I was doing this on my laptop which is running Windows 7 Beta. First the upgrade failed, then an install failed after removing Twhirl, I couldn't re-install Air because it said it was already installed, and finally I couldn't uninstall Adobe AIR.

Needless to say, I was a bit frustrated. I posted a query to Twitter to see if anybody else was having this problem. One person responded that they were and knew some other that also had the issue. I poked at it a bit, but didn't make any progress and left it alone for a bit.

Last night I decided to figure this thing out and was successful in being able to manually remove Air. After a re-install of Air and Thwirl, all was right with the world. Below are the steps I took to remove Air.

1. Delete the Adobe Air files from your system.

Delete "C:Program FilesCommon FilesAdobe Air".  Of course, change the drive letter if necessary. You will need to have administrative access to do this.

2. Remove the uninstall registry key for Adobe Air.

On my system the key was here:

HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionUninstallAdobe AIR

Use regedit  to do this. Remember to be very careful when mucking about with regedit. You can seriously mess things up. Again, you will need administrative access for this.

3. Re-install Adobe Air

Install Adobe Air again just like you did the first time.

Hope this helps and let me know if you find a simpler way.
