[wix-users] installation procedure

[abi navigator]

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.
