Cannot install no matter what I do!

I've officially done everything. I've uninstalled everything I can think of. I've cleaned the registry until it sparkles. I've removed all directories having anything to do with VS or SQL. I've even run the uninstall tool multiple times and been told everything is OK. However, SQL Server Express STILL tells me there are "beta versions" of stuff on my machine. Do you have any suggestions, or should I just give up in disgust?!?!?!

Occasionally, this has proven to be quite a headache.

Here is the list of steps and things to check that I walk through. Be precise and dilligent to check/do every one. Don't assume that it is 'almost' the same as something else you have checked/done.

Hopefully, there will be something here that will help you.

|||Thanks! I think I lied about that though; I kept digging and found the log file, which lead me to a poorly-uninstalled SQL program. I removed any reference to the program in the registry (that was no longer there anyway), and it worked!
