>MSI is a complex database.

Thanks for the information on the MSI format. I was not aware it was some sort of database. I expected it to be some specialized executable format. I now understand more why most common and cheap installer-building package do not support it.

I expect that I'll make a try with alternatives solutions, possibly one that does not support the MSI format.

Do you know whether EXE-based installers convey any significant drawbacks vs MSI-file-based ones? in terms of user-acceptance or "access rights" control?
