Update: I uninstalled the previous version and instead tried to install 4.1.0 to see if it made any difference whatsoever. I am now able to get to forum.site.com/install/install.php at least but I have several errors, a few being:

There are more as well, about 10 total warnings. Once I enter my VB Customer ID I'm told this:

Due to the following errors, the install/upgrade can not continue:
Error description:

In regards to the questions here: Yes, I have made a new database for it, created a user and password, and gave myself all privileges. I have tried three or four databases now and none seem to work. I think I'm entering the information correctly each time yet it won't accept any of it.
