Zenon runtime 6.20 SP1 Build 1 fails connection failure with soft PLC (WinLC RTX)

Zenon runtime 6.20 SP1 Build 1 fails connection failure with soft PLC (WinLC RTX)

History - I have migrated my project that had Zenon with WinLC RTX from one PC to another PC 32 bit based.
I am getting this error when I try to start my Zenon runtime  6.20 SP1 Build 1 "Unable to connect to control engine "WinLC RTX". This control engine will not be connected in the current online session." My WinLC RTX has no error at all.
