Some of our workstations recieved the the updated version of the SONAR definitions on February 14th and some did not. The ones that did receive the update are showing SONAR as "Not Installed" as well as a few other as you can see in the attachment.
The only solution I have been able to find is to remove the client from the workstation and then reinstall SEP. This brings the SONAR definitions back to a previous version. Is there a way to revert these back without this process or is there a fix to make the update work properly?
