Unable to run Themes in Windows Vista

[Aadils]

Hi,
I have downloaded some good themes from the Internet and put those into the themes Folders, When I put the theme in the themes folder, only some themes will open up and show when I double click on the shell, otherwise the theme does not show up.

Any suggestions would be appreciated

Hi,
I had also come across similar problem when I was using SP1,Are you running SP1? I am very sure some Visual styles only work in Original Vista (NO SP) while some only work in Vista Sp1.

please check your Service pack.
