cant install sigangestudio 2.# or 3.# on windows 7 pc, error #0?

hello,
I have a windows 7 desktop pc that I used to have signagestion 2.# on and always had errors with adobe air preventing me from upgrading to 3.#.  So I used a registry editor tool to remove all occurances of "adobe air", "signage" and "signagestudio" in the registry and also removed the SignageStudio folder from Program Files.
Now my pc is not letting me install Any version of SignageStudio.  It let me install Adobe Air, but when I try to install any version of the desktop studio .air file I get the cryptic error# 0.  How do I get past this error?
thanks,
david

Try downloading our air installer and installing using the Adobe Air Installer from this directory

C:\Program Files\Common Files\Adobe AIR\Versions\1.0

hello,
what's the link to download the air installer you're referring to?
thanks.
