Getting the ball rolling. Which VB6 projects are you working on?

Invalid attachment... but since you referenced the website

Front page, twinbasic.com:

Compiles to Win32 and Win64 architectures. Mac, Linux and Android compilation planned.

twinbasic.com, 'Download' header link:

This is a commercial project, though the 32-bit Windows version of the project will be available completely free of charge. Developers that need to build 64-bit binaries will either need to purchase a licence or endure a 5-second twinBASIC splash screen when their applications start.

twinbasic.com, 'Preorder' page:

twinBASIC Professional Edition includes all features from the Community Edition, plus:

64-bit Windows EXE and DLL compilation support

So this one is inaccurate only in not mentioning it's available in free edition with a splash screen, but indicates professional/ultimate compile it.

The website does desperately need an update, but still I'm not sure what's conveying the impression there's no 64bit support.

With how fast modern computers are I'm not sure assembly-level optimization is something 99% of tinkerers would actually notice or significantly benefit from. I'd love it if tB was FOSS too, and have voiced disagreements about what is in what tier, but with nobody stepping up, I can't fault the one person who is for needing to make money from something taking up so much time. The 2-4.5k number was a comparison I came up with myself for Delphi-- that is the amount they charge for a perpetual license *with no updates*. It was meant to emphasize there are equally or more expensive comparable products, not as a something being considered by Wayne for tB.
