Portal client not uninstalled?
 

Using Windows 7.

My Portal client (gameaxle.com) started glitching and became unopenable. Not being able to find an uninstall file, I simply deleted the Portal folder in "Program Files (x86)," and downloaded the installer again.

When trying to run the installer, it acts as if Portal is still installed (stupid me, been so long that I forgot the install program is also the uninstall program) and gives the option of uninstalling or cancelling the operation.

Attempting to uninstall gives this error message

"Details" gives this information:

The other option is "Continue," and it does not work does not work, obviously (wouldn't be looking for help if it did)

I tried deleting all Borland items in the registry, and running CCleaner, but no change.

Anything else I might try?
