I don't know if I'm in the right discussion group... if not, please tell me.

So here is my problem:
When using the MsiApi function MsiInstallProduct, I keep getting the return
code 1601 (that means ERROR_INSTALL_SERVICE_FAILURE)
I've checked my Msi Service. It is correctly installed and running.
Do you have and idea on what's going wrong?

Thanks in advance for your answers...
