Installing Hog4PC Error 2738

When installing Hog4PC on a new Windows 7 (64 bit) computer I am recieving a Error 2738 when the installer reaches the point that it extracts the fixture libraries. When I hit OK on the window, it rolls back the install. I have done all the most recent Windows updates. I downladed 3.2.6 and tried to install this version also. I get the same error number part way through the install. I attached a screen shot.
