I am running LK v 5.1.0201 on Win7. I get a popup telling me a patch is available, but when I try to run the patch I get an error message " Votre LiberKey est encore en cours d'execution apres la tentative de fermature automatique". How do I correct the problem and why is it telling me this in French when I have English set as the default?

I figured out why the patch wouldn't work. After clicking update, I had to use Task Manager to close the LiberKey process and then the patch worked.

Did you set up some applications to close at Liberkey Menu closure ?
