Since the software here will not install, I went looking for an alternative & found a free one.
It is called Complete Internet Repair, and I downloaded the Portable version, so it doesn’t have to be installed.
And it comes up immediately without all the hassle of installation & trying to register it.
Just giving you an alternative that you can run anytime without having to worry about if your computer crashes,
then you wouldn’t have this software, but you could have the free one I mentioned.
Hope that helps.
