1. Install version 1 of product.
2. Install update to version 2 of product.
3. After installing an update there is need to change installed features. Run an installer, select change option, add new feature from features tree. At this step MSI throws a dialog “The installed product does not match the installation source(s)”. This dialog has an option to choose installation source. I tried to set version 1 and version 2 of product as a source but in both cases receive an error “ The file ... is not a valid installation package”.
The only one way to change installed features is to downgrade to first installed version , change features then do upgrade again.
Is it possible to change installed features after upgrade without doing downgrade to first installed version?
