Some of you may have encountered an issue with installing 2013 products. They just simply will NOT install. I can across this same issue on my machine. I actually am getting lots of calls on this recently too.
I have found the culprit.
Browse to your Windows Control Panel…Start Menu>Control Panel. If you use Category view, select Uninstall a Program. If you use, Large or Small Icons, select Programs and Features.
Scroll down until you see Microsoft Visual C++2010…
Uninstall ALL of the C++2010 versions.
Once you have uninstalled ALL of the C++2010 versions, install your 2013 Autodesk products. The Autodesk products will re-install the C++2010’s back on your system and complete the initial installation successfully.
