atm i am using "VS2008" and installed "DX9 SDK Nov2008".... Is it possible to install and run "VS2005" and "VS2008" independent on one system and using the DX9 SDK? Or will i get in trouble when installing both version on one system? Because i would like to test compiled output between both versions. So i ask you, before uninstalling VS2008 or getting in trouble when running both versions. thx
