Can one install 2 different versions (4.2.1 and 4.1.4.5) of Tamino XML Server on same machine? TIA Rahul

yes, multiple versions of Tamino can co-exist one the same machine

What about the registry entries for the XTS, System Management Hub, Universal Tx platform? Does it create separate entries for each version? TIA Rahul
