VEGAS Pro 15 support

Any hope of Vegas 15 support for VoukoderPro?

If I manually install to the \Program Files\VEGAS Pro 15.0 folder (using an unused Vegas 18/19/20 option in install menu, then manually entering the target folder), I get the following behavior in Vegas 15:

• When clicking "Render As" in Vegas, instead of the Render As menu appearing, I get a simple popup box which says "VoukoderPro for VEGAS Pro, (C) 2023, Daniel Stankewitz" with an OK button.
• If I hit OK, then the main Vegas Render As window appears.
• VoukoderPro does not appear in the Render As list.
• voukoderproplug-vegas18.dll (or 20, etc.) does appear in the Vegas 15 components list.

Tried manually copying VoukoderPro files from a working Vegas 20 installation to Vegas 15 folders. Same behavior as above. Files copied:

• \Vegas Pro 20.0\Voukoder-x64.fio2007-config
• \Vegas Pro 20.0\FileIO Plug-Ins\voukoderproplug\

It would be nice to get this functionality. Newer Vegas is such a constipated clusterfudge for what I'm trying to do. Overengineering at it's finest.
