I've read the problems mentioned in that post, but I don't think we have the same problem.
I have done the suggestion by this post, but did not work for me, as I got the same error, Error Code: U44M1P28
My problem is I have not reached a point to export my AIR for iOS.
The error that reoccurs is while installing, it fails to install.
Trying to figure out another solution, I uninstalled Flash Builder 4.5 Premium, to install a new full version of 4.5.1 from Adobe's website.
While Installing, I get the following message which showed me exactly where my problem is... I have a prereleased version of AIR for Apple iOS Support.
The Question is... How do I uninstall the prerelease version of AIR for Apple iOS Support? I uninstalled FB4.5, and I removed the remaining folder after installation that was in Flash Builder 4.5 that was in Utilities. though, I still get the message above...
Any idea on how to Uninstall a Prerelease version of AIR for Apple iOS Support?! No where to be found online.
Solved... You need to install the CS Cleaner tool, and hit on Clean on the Selected CS suite you've got (most prob 5.5), and then you're good to install the new FB 4.5.1
You can get the tool here: http://www.adobe.com/support/contact/cscleanertool.html
If you install CS5.5 with Flash Builder. You can use the CS5.5 uninstaller to uninstall AIR for Apple iOS Support. Just check that checkbox is fine. I think this is the easiest way. BTW, I like the CS Cleaner Tool.
None of these methods are working for me...
I have reinstalled the software several times, I have rebooted, I have used the cleaner tool. Nothing. I still can't get rid of this thing so I can re-install with 4.6.
