I certainly agree that it's a machine issue, although it's strange that I'm still able to install windows updates, notepads, video editors etc without problems. I just tried to install Java - and got a similar error. According to the Java error, msiexec.exe is currently processing another installation. It seems to only be a problem when attempting to install programming languages. Could a clean boot help? I saw that recommended somewhere.
