What I mean is that with Home Premium, there are no such thing as run in compatibility mod. This feature, even though it looks available, isn't.
First thing first. Even though swkotor2 "installed" fine, it doesn't mean you'll be able to run-it. Try-it before installing TSL RCM 1.7 and you'll see not being able to run-it has nothing to do with TSL RCM. As I said, you should try to disable movies!!!!
Here's how: -go into your Star Wars Knights of the Old Republic II folder
-Run "swconfig.exe"
-Check "Disable Movies"
-Click apply
-Click close
-Run the game (with or without TSL RCM......)
