"no program start menu found", pless help?

im trying to install warcraft 3 at the moment.

the error "no program start menu found" comes up.

iv tried to fix it by going to:

"HKEY_CURRENT_USER\Software\Microsoft\Windows\Current Version\Explorer\Shell Folders"

and adding a string as follows.

C:\Users\%USERNAME%\AppData\Roaming\Microsoft\Windows\Start Menu\Programs

but the error still comes up.
