Installation Problem with FS9 and Windows Vista

I have a Gateway computer with Windows Vista. I had FS9 installed in it. I uninstalled FS9 because my computer began crashing in the middle of my flights. I try to install the game again, but for some reason, the intallation never starts. What can I do?

I suspect the problem is related to the fact that my computer installs windows updates automatically. Might windows have been updated in such a way as to start having problems when running FS9?

Help!

The problem is that you still have some "parts" left on your computer.
The machine has to be completely free (including registry) of everything FS9.

Follow this closely and then you can reinstall.

Best way to uninstall.
