I have downloaded the 2010 version and attempted to install it several times I have run the install program under normal user, ran it as administratior, restarted my computer with only necessary windows files. I have downloaded the program 3 times. Wall with the same results, when I try to start the program, it tells me that not all registry items copied properly and that I need to reinstall from the same location to correct the problem, and it doesn't fix the problems.
