Problem installing 3.315 on MY Vista system

[MTUSUPPORT]

There is something in your system that is messing this up. This is what it states to me on Installshields website about this problem. They said its fixed by doing what I just told you above.

Its not a vista problem, but something with your OS.

When you installed Vista, how did you install it? Did you reformat your computer and do a clean install or did you upgrade from Windows XP?

If you upgraded, most likley this is your problem, and you would have to reformat your hard drive and then reinstall Windows Vista as a Clean Installation.
