When you use the Sync App to integrate with Sage 50 or Quickbooks Desktop, you may need to change the start-up type of your Sync App to a Console or Service application.
This could be because you're receiving an error message, or the app wasn't installed correctly.
To change the start-up type of your Sync App, do the following:
Open your computer's Task Manager, select the Services tab at the top, then click on Open Services at the bottom of that window.
When the Services Window opens up right-click on the AutoEntry.DesktopSync.Service and select Stop.
Once stopped, right-click on AutoEntry.DesktopSync.Service again and select Properties.
Under Startup Type select Disabled.
Open the Sync App again and ensure you are able to view your company list.
The Sync App is now running as a Console application.
