Q: Unknown program prevent W7 to shut down

When shutting down the W7 system I receive message on screen:


(Waiting for) CL RC Engine3 Dummy Winidow

This program is preventing Windows from shutting down.


Then one error window opens with the following text:


In the top frame of window:”CL  RC Engine3 Dummy Winidow: QPService.exe – Application Error”


Inside window: ”The instruction at 0x0026c3f8 referenced memory at 0x000005d The memory could not be written.  (These data differ from each shut down)

Click OK to terminate program.



Yes, I have understood it can be part of the Quickplay installed by HP.
Computer is HP Pavillion
Have uninstalled Quickplay and error msg gone. (Perhaps not the correct way.)
Thanks anyway

Did this solve your problem?

Sorry this didn't help.
