in MVC++, i make an ALT COM project using the ALT COM AppWizard, and when it i compile it, it hangs at "performing registration", and hittin "cancel build" doesnt do anything. i end up terminating the process with ctrl-alt-del. it was working fine a few days ago, and then i cleaned up my hard drive some, but i dont think i deleted anything to do with the studio. i reinstalled the studio anyway, but it still messes up.

Did u play with the global functions named DllRegisterServer? or maybe main App class''s InitInstance function? Because those are called in each compile.. try adding some AfxMessageBox("la la"); lines in those..

hope that helps.
