I recently used a special tool designed to fully remove all traces of .NET framework from a Windows 7 install. I did this because I believed the files to be corrupted. I then tried to reinstall 2.0 because I need it for a program to work properly. Only I can't reinstall because the operating system still says I have .NET framework installed, even though this removal tool supposedly removes all traces registry entries & files. And it said it uninstalled everything fine. So what do I do now? exact error message: This product is already a part of the operating system additional note: disabled .NET framework before the uninstall tool ran On a side note, a matter of less importance. I have a file that has somehow been added to a to be burned to CD/DVD system with Windows 7 that keeps showing up along with the files on any CD or DVD I put in my burner. And I can't get it to go away. If I delete it, it just comes back. How do I tell Windows 7 to screw off because I don't want any files to be placed in a to be burned to CD or DVD state? Thanks in advance for any help anyone might be able to provide!
