Error. Another user is running this copy of R-Viewer

In trying to run RU Viewer on Windows 8.1, no window opens on run. Attempting to start again shows "Error. Another user is running this copy of R-Viewer"

Any insight appreciated.

Hello,

The Close button (the red button at the top right corner of the window) in the Viewer hides the program into the system tray . To quit the Viewer use File -> Exit command.

Hope that helps.

Hi Conrad,

The system tray isn't showing the application as running and it doesn't show on the desktop when run.

I recommend rebooting the PC and then trying to run the Viewer. Let me know if that didn't help.

No different behaviour after reboot.

Hello,

Make sure that the program is not blocked by antivirus software. I would recommend explicitly adding the path to the Viewer installation folder to your antivirus software exceptions.

So far I reckon no other explanations for such behavior other than extremely strict security settings or antivirus software activity.

Hi Conrad,

Added the Viewer exe to Windows Defender exclusion list. Same result.

The portable version of Viewer does run OK, on the other hand.

If so, then the installation got corrupted somehow. Please, uninstall the Viewer, clean up/delete the installation folder and re-install the Viewer this time as an administrator. This should help.
