To stop table conversions
Close the Workbench.
On the Deployment Server, open Task Manager (press CTRL+ALT+DELETE and select Task Manager). Go to the Applications tab. Select Installation Workbench. Click End Task.
Delete waiting jobs from Submitted Reports (GH9011).
Enter W in the Status QBE and click Find. If any are shown, highlight all rows and delete.
All conversions should now be stopped. There are several more steps involved with cleaning up the database and resetting Table Conversion Workbench. See Restarting Workbench below.
You might decide to leave one or more table conversions running but close Installation Workbench and restart the remaining conversions. See Restarting Workbench below.
Installation Workbench should not be closed if Table Conversions are running normally. Only close it if problems have occurred and conversions need to be restarted.
