Hello,
You are right in that there are some requirements for Sprinter integration alongside of UFT. Sprinter 12.01 and Sprinter 12.20 have some specific versions that must match up along with a registry key manual addition requirement.
Sprinter 12.20 can be installed on the same machine as UFT 12.02 only. Sprinter tests cannot be run in Power Mode while UFT is running and UFT cannot run while Sprinter is running in Power Mode.
Installing Sprinter 12.20 may interfere with a manually entered UFT registry entry ''AbortIfHangInSendData'' under HKEY_LOCAL_MACHINESOFTWAREMercury InteractiveQuickTest ProfessionalMicTest.Workaround: On machines with UFT 12.02, add this registry entry manually after the Sprinter installation.
Similar setup for Sprinter 12.01, just to make mention. Sprinter Service Pack 12.01 can be installed on the same machine as UFT Service Pack 12.01 only. Sprinter tests cannot be run in Power Mode while UFT is running and UFT cannot run while Sprinter is running in Power Mode.
Same registry key addition applies as well for Sprinter and UFT 12.01.
Generally speaking, results seem to show that UFT should be installed first and Sprinter after. And the versions must sync up or things will just not work properly.
