You can create a dummy MSI file that contains only this merge module and then install it by calling msiexec.exe. To call msiexec.exe, use Exec, ExecWait, ExecShell or the nsExec plug-in.
didnt work. msiexec runs the msm file but it doesnt do anything. i think it's because in vs i need to put a keycode for it to compile i dont know how to do it now.
