mjammer, It would help if you could write about what exactly the errors are, this way we can only guess what the problem is. It's possible that you haven't really updated your OS for too long, so try installing Electrum after you do that. Also check that some of the security software is not blocking the installation (your antivirus).
Hope your computer also have enough memory space for the wallet installation space.
I wouldn't say that the problem is the lack of disk space, because Electrum is not demanding on that issue - although let the OP check if it is really left on less than 100 MB of disk.
