I have seen this before posted with no answers. prl_cc.exe is often locking files. I am seeing this most often when running a setup program that deletes a directory then tries to recreate it later on. I am running window 7 in Build 8.0.18101 (Revision 797180; September 5, 2012) Here is a screen shot showing a tool called Unlocker that is showing this process is the cause. Ending the prl_cc.exe process and trying again allows it to work. I would like to know if there is a way to prevent this and if now will killing that process regularly hurt anything. Thanks.
