Before doing full install of DLLs, worst case, try to run the .exe standalone first and see if it will load. Could be that Win 11 already has these dlls.

For the items that are dll self register and don't already exist on your system...

Open a command prompt in Admin mode.

cd /d C:\windows\system32
regsvr32 dllname

for the .tlb, I presume it's already in Windows 11

The ones you are most interested in are

MSCOMM32.OCX
msvbvm60.dll
comcat.dll

vb6stkit.dll is the VB6 setup dll and don't think you will need it.
