My computer is a iMac (20-inch, Mid 2007). The model identifier is iMac7,1. The processor name is Intel Core 2 Duo, which means I have a 64 bit machine. The Apple web site Boot Camp: System requirements for Microsoft Windows operating systems shows the only downloadable Boot Camp support software for my Mac is for the 32 bit version of Windows 7. I can successfully install the 64 bit DVD installation versions of Windows 7 and 8 on my machine. The problem I am having is with the Boot Camp Support Software 4.0.4033. When I follow the instructions and double click on setup.exe, I get the following popup.
How do I successfully install this support software and avoid this popup?
