Make COM Register silent for EXE

[wellilein]

COM registering an EXE file is already possible. Unfortunately there is always a message which blocks the build process.

If not by default being silent, I suggest a silent checkbox.

I am currently using a workaround
%DOSCMD% C:\...\ToRegister.exe -s -regserver

BTW: Registering DLLs is already silent.

Thanks, Thomas
