This error occurs when running Quark 8.5 on one of the eight client computers.

"Can not connect to Quark License Administrator because the QLAClient.properties file can not be found Contact your system administrator - 4117"
I deleted and reinstalled Quark8.5 but it does not run with the same error.
The QLAClient.properties file is located in C: \ Users \ Public \ Public Documents \ Quark \ QuarkXPress 8.
What do I need to do to solve this problem?
