Having 32 spare bits, for a total of 64 is making certain pieces of software not work or install on my newest desktop. Last night I decided to install Windows 7 Professional on the desktop. Because the desktop is a 64 bit system, I decided to install 64 bit Windows. Turns out, that was a bad idea. It would appear that one of my favorite 32 bit games has a few 16 bit components, such as the installer, which are not supported in a 64 bit OS. I suppose because of progress I am supposed to simply accept this fate and move on to a new version, but unfortunately, there is no new version. MotoRacer is no longer produced, primarily because the company that made the game no longer exists, but worst yet, there are no other games that will substitute it adequately. There are also concerns with some hardware not having supported drivers on the 64 bit platform.
I installed Windows 7 Professional 64 bit, but unfortunately, it did not quite work out for me, so I am now back to running Windows 7 Professional 32 bit for now.
