A good while ago, Real Software released RealBASIC 5.5.5 free for all ex VB6 users when Microsoft killed VB6's support.

I lost my installer for it quite some time ago, and wanted to mess around in RealBASIC whilst I was bored. After searching around for a few minutes, I found out that they have an FTP server running with all their older versions for people with my problem, and people who were curious as to what the previous versions were like.

The link for the root folder is:

RealBASIC 5.5.5 can be found here:
I still run RB 5.5 since that's the only copy I legally have the key to do so.

I love it, classes are a breeze.
