A few weeks ago I uninstalled all of my versions of Microsoft .net framework from my PC because I didn't think it mattered and I was trying to free up more hard disk space. But it turns out I do need the program and Ive tried installing every version of Microsoft .net framework from the Microsoft site and I receive an error during all of the installations and the errors just say something like this "Microsoft has encountered an error and is unable to complete the installation." The errors are very unclear. I do not have my original PC disc so I cannot install the original copies on my pc. What should I do?
