Hi Bob,
Thanks for posting in the community! Sorry to hear about the issues you've ran into recently.
This error can be caused by the GoToMyPC viewer files being erroneously "in-use" according to Windows. Since a reboot of the Client didn't resolve the issue, please follow the steps below from the Client PC:
Step 1: Run the Launcher Error Tool- Download the tool here.
- Extract GoToOpener_PermissionsFix.bat
- Right click on GoToOpener_PermissionsFix.bat
- Select Run as administrator
- Wait while a command prompt window appears and disappears
- Attempt to connect to the computer again
If the Permissions Fix tool does not work, you may need to manually disable sharing of the temp folder:
- Hold the Windows key and press R
- Type %temp% in the run window
- Navigate back one folder
- Right click on the Temp folder
- Select Share or Share With
- Click Stop Sharing or select Nobody
- Click Done
Step 2: Delete GoToMyPC Viewer files- Uninstall the launcher
- Reboot
- Navigate to C:\Users\\AppData\Local\Citrix\GoToMyPC
- Delete every file named gotomypc_XXXX.exe
- Navigate to C:\Users\\AppData\Local\GoToMyPC
- Delete every file named gotomypc_XXXX.exe
- Empty the recycle bin
- Reboot
- Attempt connecting again
