Twhirl & Adobe Air: Catch-22

My favorite Twitter app, Twhirl died on me two days ago. Actually, it’ snot Twhirl itself, the error message clearly identifies Adobe Air, stating the installation is damaged.

Fixing it should be easy: just reinstall Air. Except… I can’t. Adobe installer says: This version of Adobe Air is already installed on your system. Yeah, thank you, I know, but it’s corrupted.

Oh, well, next step is uninstalling Air, then installing it again. Except… I can’t do that, either. A quick search shows I am not alone: several users report that in Vista Adobe Air does not show as an installed application, hence you can’t uninstall it, either.

Catch-22.smile_angry I hope Adobe proves otherwise.

Update (5/16): I found a forum tip: run the Adobe Air installer from a command prompt with the -uninstall parameter. It worked, I got Air off the system, then installed it again. Guess what: Twhirl still reports damaged Air file. Next I thought I would uninstall Twhirl – I can’t. Unlike Air, this one is listed in the Control Panel, you can click on Uninstall – nothing happened.

I’ve been off twitter for several days now, have seen evidence of users reporting this issue but received no response whatsoever from either Twhirl or Adobe yet. This s*cks, big time.

Update (5/16):  Adobe Support came through, the recommended the Windows Installer Cleanup Utility. It helped, although not in a straightforward way. Steps involved:

  1. Install Windows Installer Cleanup Util
  2. Cleanup Adobe Air and Twhirl
  3. Now Adobe Air shows up  in Control Panel, so I click Uninstall.  Error: This app requires a version of Adobe Air which is no longer supported.  Oh, well, on to the next steps…
  4. Install current Air version
  5. Try Twhir: still shows Air error, the installation of the application is damaged.
  6. But there is hope, at least now I can uninstall Air from the Control Panel.
  7. Install Air again (same installer I just did minutes before)
  8. Try twhirl again: still shows “damaged” message.
  9. Try uninstalling twhirl from control panel – can’t.  Air error again.
  10. Try re-installing twhirl again.  Can’t: already exist in current location… but that’s a good clue.
  11. Installed Twhirl in new directory, and voila! it works now.   To bad i have leftover crap from previous install.

In the end, after several days and many  hoops, I am back on twitter (twhirl) again.   Still like twhirl as a product, but their support sucks. thumbs_down Non-existent – at least on the very media they live and die for: twitter.   5 calls for help over 5 days left unanswered.  I received better support from Comcast on Twitter.


  1. Thwirl stopped working for me a couple of days too. I haven’t looked into it yet but I bet it’s connected to what you’re reporting.

    do you follow me @

  2. Peter, see update above.

  3. I have this issue in Linux. I am sure it is not going to get fixed for a long long time for me.

  4. I just uninstalled in command promt… I was then able to uninstall AIR and twhirl from add/remove programs. Then kill all twhirl.exe processes. Then delete the twhirl directory in Program Files. Then just reinstall AIR and Twhirl. Don’t confuse people by making it more complicated than it has to be.

    Thanks for the info. I was finally able to get Air and Twhirl uninstalled and reinstalled after using your tip about the Windows Installer Cleanup Utility. 🙂

  6. This post was just what the doctor ordered.

    Glad I found it, thought I believe my original problems were caused by conficker virus and related frustrations.

    Thanks for writing.


  1. […] Twitter client.  Want to use Twhirl, need Air, it’s that simple.  If you read my Twhirl & Adobe Air: Catch-22 situation, I must have recorded 6-8 installs just in that nightmare, let alone the other PCs I use […]
