Not true, I maintain the VB6 and VC++6 parts of our system on a Win 11 machine. Search a bit and you will find instructions for installing them successfully.

I think the installer wont work and needs some workarounds to convince it to install but the program should work.

I have not tried it myself, but apparently it can be done.

I coded and compiled a vb6 program last week on windows 11.
