error while installing visual studio 6.0
 

i am trying to install VS6 but it is giving following error.

setup has encountered a problem in launching the followning command line:
"wpie15.exe" /q:a/r:n.
if you have a system directory that contains a % sign, or the directory names *starts* with a space (i.e. 'C:\win95\system'), then setup will fial. please restart setup and ensure your system directory names does not contain the aforementioned problems, setup will now abort...

but i could not find any such directory with a % sign or space ...can anyone solve my problem asap?
