RemoveExistingProducts removes the products who's ProductCodes are found in the union of all properties found in the rows of the Upgrade table not marked “detect only”. The property values are semicolon-delimited lists. If you add ProductCodes to the list, they will also be removed. If, OTOH, you remove ProductCodes from the list, they will be ignored.

What about the uninstalling? What I want to achieve is that only version
that resides in the same directory is
 uninstalled and all other versions are preserved (side by side
installation support). As far as I can see RemoveExistingProducts
uninstalls all versions
and there is no option to uninstall specific one. Is there any other
possibility how to do it?

For each product  Product/@Id is auto generated, UpgradeCode guid is a
constant and version is modified.

Thanks for support.
