I have two users that are suddenly receiving this Error when launching our Desktop Automation Solution which is Plug-in version 8.0.1082. There has been no update to the solution. These users did however just receive updates for Adobe Flash Player 28 NPAPI and ActiveX, and many updates on Microsoft Office Professional Plus 2013. I have no reference to the MT Extra font in the solution. Uninstalling the Flash Player had no effect on the error. I also installed just the Flash Player on another system, and it did not cause an error.
If anyone has seen this error and has been able to track down the update that is the cause, please share.
