I have tried to run my TC3 script on the latest beta release on Windows Vista Build 5270. What I found is the return of all my Sys.OS call return a empty string.
Is there any solution for this or we need to upgrade our TC3 to TC4?
This is a known problem for TestComplete 3 - this property doesn't work under Vista.
In TestComplete 4, this property should return a valid string.
However, we cannot guarantee stable working of TestComplete in this environment until Windows Vista is released.
