Hello,
What version of Windows do you need to support? Detecting COM ports is not as easy as it used to be, and Windows 10 doesn't use the same mechanism as Windows 7/8.
I develop using Builder C++ 10.1 and will provide a binary install file. Do you need a logo on the application or a help file?
Let me know if I can be of service.
Regards,
Stuart Borden.
