Try running the program in Vista or XP compatibility mode. Right click the .exe file, select Properties, then on the Compatibility tab select Vista first and then XP if Vista fails. Also click Run as Admin. Now run the .exe.
What I would do if I have to have those programs and they will not install, is save a Windows 7 Backup image externally of the current install. Then reimage onto the same HD a backup image from one of the computers that succeeded with install to see if Windows 7 will start up, swap out all of its drivers
and run normally. I have done this about a dozen times when Windows 7 install fails and it always worked fo me. Backup Complete Computer - Create an Image Backup
