2012-10-14 Update: I tried the fix another forum member posted about silent install..It worked!
In an elevated command window, <Your Path>\AdobeAIRInstaller.exe-silent
MT
Original ----------------------------------
Same problem many report and same frustration that the steps outlined by Adobe do not fix the problem. Win 7x64. Acrobat X Pro, Elements 10, Digital Editions and Premier 10 installed. MS installer/uninstaller cleanup tried. Uninstall of AIR done. Attempted update of AIR opens a new window every time I click "I Agree" and ultimately fails with message Sorry, an error has occurred...Please contact your administrator (I am the Admin). Defunctioning the Antivirus (ESET) does nothing. Registry cleaning useless etc.
