"Run Time error 339:
Component MSCOMCTL.OCX or one of its dependencies not correctly registered; A file is missing or invalid"
Something I did? I'd like to check out the program.
No, you didn't do anything wrong. Your PC likely doesn't have that particular OCX file installed & registered. The easy fix would be for me to create a setup.exe install package and include the runtime files, rather than just providing the application executable file only. That should allow it to run on any PC. I'll do that with my next build, but with a disclaimer. Running a setup file will copy system files and modify your registry, and while it should work just fine, use it at your own risk.
I'll make a setup package available later tonight or tomorrow.
