When trying to login to the IM manager console there is a popup error that it can't reach the controller.
Windows Task Manager shows controller.exe is not running.
Controller log is not updating.
Opened a command window and changed directory to the $\nimsoft\robot directory and ran controller.
It returned this error:
The program can't start because nim_shared.dll is missing from your computer.
Viewed the files in the \robot directory and found several had been renamed with a .797 extension.
Removed the .797 extension and then restarted the Nimsoft Robot Watcher service.
