Thanks allot! I'm not warring about size of the package. I have another case. The runtime part of our software can be shipped as a stand alone MSI or as a merge module. And the point is that this two edditions (MSI & MSM) are incompatible. Standalone runtime can not be installed on the computer where already installed software with merged runtime and vice versa.
That's why I want to know is it possible to find out was an MSM installed before or not... Best regards, Peter G.
