Okay so I downloaded the PSDK and used the register directories button in the start menu in the psdk folder.
But I remember other steps being necessary to be able to compile and run a win32 application, having to do with vc_corewin or something or other. Unfortunately the link that pointed to the steps in the sticky post at the top of this forum goes to somewhere else now. It was a bit of a complicated task, requiring fine tuning of a couple lines of codes in a couple files, any help?
