PCDLRN.exe closing issue is one of PC-DMIS most coming issue that never been completely solved. PC-DMIS is the only software that I have ever used that needed the Task manager to end the software at this level. How many years will it take Hexagon to completely fix this issue. If you use PC-DMIS, you will sooner than later get to know the Task Manager very well.
