Display fusion locking random files it has no business touching, let alone locking.

4 discussion posts
I was recently trying to update KMPlayer 64X while display fusion was running. The installer threw an error stating that C:\\Programs\KMPlayer 64X\VSFilter.dll could not be updated.

I then downloaded one of many file-lock managers and determined that DisplayFusion.exe had a lock over the file. Once I kill it, the installation continued without any issues.

What's going on here?

Strange, if you head into the compatibility tab in DisplayFusion, add in the application, and check off "Disable Application Hooks", does the issue persist?
