I am running Windows 10 on a MacPro1,1. I deleted Mac OS X and simply installed Windows on the Mac Pro as if it is a regular PC. I used the Boot Camp drivers and all is working well except.... I notice that I cannot install redistributables such as older DirectX or Visual C++. The installer just hangs and refuses to proceed. I don't know if this is a Mac Pro hardware issue or a general feature / bug of Windows 10 (I am running Anniversary Update build). Can anyone here using Windows 10 on a Mac Pro help me?
