"simply" the topic:
I want to install multiple instances of a software on the very same machine. This should be steered by an MSI parameter. Example:
software.msi INSTALLTYPE=variant1 should install in PROGRAMFILES\Software_Variant1
software.msi INSTALLTYPE=variant2 should install in PROGRAMFILES\Software_Variant2
on the same machine. They differ only on 4 to 5 files and different ODBC settings.
How do I do a side by side installation? Me thinks that this is not possible due to the same productcode of the MSI, but since you are the experts...

best regards
Olaf
