Windows 7: Can't Install Adobe AIR

I am troubled by this problem a long time.
Here are things I have done to try to fix the problem:

1) Uninstalled
2) Used Windows Installer Cleanup
3) Used CCleaner registry cleaner to remove all traces of Adobe AIR
4) Deleted "Adobe AIR" folder in the "C:\Program Files (x86)\Common Files" path
5) Installed with administrator privileges

Guys, I know this is an old thread but still comes to the top of the results when searching in google reagrding issues installing Adobe air and the resolution does not seem to be out there on the WWW.

Within windows 7 in order to install Adobe Air you need to do a silent install, so copy the AdobeAIRInstaller.exe locally for quick sakes and assuming you have admin rights to the machine, at the command prompt type the following:

adobeairinstaller.exe -silent

Hi guys, i've found solution.
Remove from registry keys for adobe air:
HKEY_CURRENT_USER\Software\Microsoft\Windows NT\CurrentVersion\AppCompatFlags\Compatibility Assistant\Persisted

This thread is one of the top items returned in a Google search, so I'm adding my solution here in hopes others can be spared the misery of Adobe Air install problems. Windows 7 64 bit; just did a clean install and am reloading programs. Current version of Air would not install, I kept getting this in the install log: (user name changed to protect the innocent)

I deleted all references and remnants of the program from the hard drive, including deleting the registry key as posted earlier in this thread without any improvement. (BTW, CC Cleaner does not find and eliminate that key.) But then I tried it all again AND changed permissions for c:\users\XXX\appdata\local\temp\ so that SYSTEM had full permissions. Previously SYSTEM had none. Air installed flawlessly after that.

Hope this helps someone.

Welcome to the Windows 7 Forum. I don't understand how System lost its permission. The only thing I can think of is that the UAC was not administrator.

Layback Bear: That fix has worked for me on two separate Win 7 installs, both with a single user/admin. It is odd that SYSTEM had no permissions for that folder. I have the bad habit of "taking ownership" of folders willy-nilly when something doesn't work, and I can't remember whether I did so for this folder or was always owner. But taking ownership shouldn't remove existing permissions for SYSTEM should it?

I don't really know because I have never tried. You had it happen on two different installs so I'm guessing that it does.
