#### Troubleshooting Vista

Issue: The Vista diagram does not open in the Engineering Client, even after the Engineering Client license is applied to the server.

Workaround: For the Vista diagrams to open properly, first delete the trial license from the server, and then apply the Engineering Client license to the server.

Issue: After completing the upgrade, Vista will not run. When it is launched, you see the splash screen, but before you get to the login screen, Vista crashes. You see a dialog from the operating system stating that Vista has stopped working.

Cause: This happens if your PME config\cfg\ud directory has a `global.log` file. `Global.log` is a file that is created when you add a Global Event Viewer to Vista. The old file format from ION Enterprise 6.0 or earlier is not compatible with PME 8.2 Vista.

Workaround: Delete `global.log`. You must re-add a Global Event Viewer if you want to use it in your upgraded system.

Issue: You see a configuration error in the Vista diagrams as shown below. Possibly, the ION and XML files have been updated in the new PME 8.2 system.

Cause: The Vista diagram refers to the old ION and XML files located at …\config\translator folder.

Resolution: Delete the ION and XML files from the …\config\translator folder and re-do the MDI configurations manually.
