Cannot reinstall mySQL

[Eli Mattrick]

Hi,
For one of my classes I needed to install MS Access and mySQL. The first time around installing MS Access was giving me so much trouble to the point where I had to system restore. But while system restoring it uninstalled SQL, but left all the system files affiliated with it. This caused even more problems it seemed.

I now am unable to install mySQL. I've gotten a variety of errors while installing from not being able to apply security settings in the very last step of installing SQL to the error I have now which is the following: "Internal Error.(Object reference not set to an instance of an object. The installer will now close.". This error pops up whenever I try to run the installer.

I've tried a lot of different things to resolve this issue. I have cleaned the registry, deleted all files I could find relating to mySQL, and uninstalling. Nothing has worked. System restoring again is not an option at this point as I don't believe I have a point that will go back that far.
