Error 1608: unable to create installDriver instance, return code -2147221021 when try to install Microsoft Flight Simulator 10.

Original Title: 1608: unable to create installDriver instance, return code -2147221021.

Got this error code when I tried to reinstall FSX, (MS flight sim 10). I have been having problems with the windows installer in the services section. It doesn't start all the time and I have to go in and start it. It is set to start automatically in the properties area. I have re-registered it a couple of times but this doesn't seem to do anything. I also can;t install teh "fix it for me tool". 

 I also have a problem with the Install and remove programs window. It never populates the window with any of the programs or updates. I am Running win xp with service pack 3. INtel pentium D dual core, 3.2 Mhz with 4 GB of ram. OS is installed on a One TB drive.

I also have PC cleaner Pro installed. It does give most of the installed programs to add or remove, but I don't think the list is complete.

I seem to have expereinced most of these problems after installing SP 3.

I had a hard drive fail a few months ago and at that I installed the one TB HD and put the OS on it.

I retrieved the important files from the fried drive using puppy linux. That was a life saver.

Any help is welcome.

Thanks in advance,

     Bob G.
