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.

  2. You may ask yourself why I am posting about hard drive failures. Never forget that one leg of the CIA triad is availability. If you have Seagate drives, you might want to check if you are effected.

Wireshark and Windows 7

by kriggins on January 12, 2009

in Uncategorized

UPDATE - November 13th, 2009: I have just successfully installed Wireshark 1.2.3 on 64-bit Windows 7 Ultimate. Version 1.2.3 includes WinPCAP 4.1.1 which supports Windows 7. I did not have to do anything special. I simply installed the Wireshark package.

UPDATE October 22nd, 2009: Johan indicates in the comments that version 4.1.1 of WinPcap has been released. He says that it works fine with Windows 7. I would install version 4.1.1 of WinPcap first and then install Wireshark and say no when it asks if you want to install WinPcap. I need to confirm, but the rest of this post should still hold true.

-------

I needed to do a packet capture on my Windows 7 box. With a certain amount of trepidation, I downloaded Wireshark (1.0.5) and ran the install.

Unfortunately, it did not work. However, I did not install the NPF driver as a service. I uninstalled and reinstalled, setting the NPF driver to start as a service.

Success. So, if you are installing Wireshark on Windows 7, make sure to check the option to start as a service. This allows non-administrative users to use Wireshark. I suspect UAC is getting in the way, but have not dug into it yet.
