on a win8 64bit system I get the following behavior.
vvvv 390b7c6f120559df66f06c46982e84d6d97b1572 crack.exe in x64 vvvv report visual c++ 2008 not installed. after installing vc++ 2008 from link in crack.exe the vc++ 2008 is still red. and vvvv fails to start.
390b7c6f120559df66f06c46982e84d6d97b1572 32bit works without trouble
