Adobe AIR Installation

Hi , I recently had problem with Adobe Reader ( Asking for it to be re-installed)  then checking I found my other Adobe products had the same issue.

So I uninstalled:

Reader

Flash

Shock Player

AIR

I managed to re-install all but AIR. which says error Code 7

I have tried the Microsoft Fix, Running the exe program as administrator but without luck.

Most reported issues in the forum are several years old , but I cannot seem to find a clear solution.

Any ideas on how to proceed ?

Thank you
