Can you see if you can find this:C:\Program Files\???????CS1.5?????
I'm not sure if it's a folder or a file. You might just need to look for the CS1.5 - I'm not sure if the question marks will be question marks or some other character. If you can find it, can you take a screen shot of it and post it here, like you've done with your prevx results?
