\tf.exe is not a valid win32 application

Question

Whenever i try execute TF.exe (via Windows Explorer/Command Prompt/VS2005 Command Prompt/VS2005 x64 Command Prompt) i get the error:

"C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\tf.exe tf.exe is not a valid win32 application"

This was working before, don't remember exactly when it starting happening or why (possible due to some dumb windows/visual studio/.net security update, is my guess)

Odd thing is that Team Foundation Server operations work perfect via Visual Studio.

Anyone has a clue?

Windows XP Pro SP3 (x86)

Visual Studio 2005 (8.0.50727.762)
