Vista - Explorer files don't match folders-Please Help

While installing a program, the process was interrupted and the install created 62000 files using 160gig in my syswow64 folder virtually using all my hd space. However when you go into the syswow64 folder, there is only about 2000 files and 1 gig of space used. I have set the folders to show all hidden files. When I go into the ms dos prompt and do a directory, the files match the 1 gig data. I can't delete these 62000 files and free up the 160 gig space because I don't believe they are actually there on the hard drive but explorer thinks they are there.
Is there any way to rebuild, sync, or otherwise get windows explorer to recognize the correct amount of files that are actually in my syswow64 folder.(2000files 1gig and not 62000files 160gig)
Please advise. I am lost.
Thank you.

Have you tried using disk cleanup to remove temp files?
Have a look at CCleaner.

Hello drjoyce1,
You could try a system restore and re-install the program that cause all the bother, this time with no interruptions.

Hope this helps, good luck and post your results, thanks.

The system restore files were accidently deleted with a clean up operation using tune-up utilities. I have tried to reinstall the program with no luck. I am not sure now if this is a vista problem or some type of virus. My virus software is not detecting anything. Thanks for your response. I am open to any other suggestions.
Thank you.

I have used tune-up utilities to cleanup the disk and remove all temp files. I also did a defrag hoping the defrag would notice the files weren't actually there and correct the problem with no luck. I haven't used CCleaner. Would you still recommend it even though I did use tune-up utilities 2009. Thank you for your response. I am still open to any other suggestions.
Thank you.
