Cannot update, uninstall or install Adobe AIR

I have a particularly puzzling problem.

AdobeAIR has never allowed me to update it. Ever. I have received countless notifications over the years, but everytime I clicked update, I received an error message. The version I have is 3.7.0.2090. I have attempted updating it to 16.0.0.273 all day. I continually receive this message:

"An error occurred while installing Adobe Air. Installation may not be allowed by your administrator. Please contact your administrator."

I have downloaded the latest version and selected "run as administrator". That didn't work. I tried creating a new administrator account on my pc and then selected "run as administrator" using that account. All to no avail.

I figured I might uninstall the version I have, so opened control panel (I'm running Windows 7, btw) and looked for the application in the Programmes list to uninstall it. However, the app was not listed. Anywhere.

I then found, in these forums, someone had a problem with updating and/or uninstalling and attempted a manual removal of some register keys. So following their instruction, I did that. However the issues and error messages remain unchanged.

I am at a complete loss. I cannot uninstall an app that doesn't exist. But I can't update the version I supposedly have.

Any help with this troubling issue would be most welcome.

Kind regards and desperate pleas...

Edit: I have also tried repairing this problem using MicrosoftFixIt. That did not help.
