Hi Mac Main ,

Thanks for reaching out. Given that the error states "Sage BusinessVision control file for company is being used by another user," this typically relates to a licensing issue, especially if you recently upgraded to Sage BusinessVision 2023. If only one user can log in after an upgrade, it's possible that the temporary licenses have expired, and the permanent Actian licenses have not been installed.

Here's what you can do:

1. Check if the Actian licenses have been installed. If not, you'll need to install the Lanpack license for Actian. You can do this by running launch.exe from the installer and following the steps to install the license.
2. If the licenses are in place, perform a Pervasive/Actian Communication Test. Depending on the test result, you may need to restart Pervasive on the server, change the Listen IP address, or reinstall Pervasive.
3. If you encounter errors when opening the BVCON.FIL in Function Executor, you'll need to check user permissions, the number of licenses, and potentially reinstall Pervasive or Sage BusinessVision.

For detailed steps, please refer to these articles:

• Troubleshooting steps for Sage BusinessVision Control file issue
• Only 1 user can log in Sage BusinessVision after upgrade to version 2023

If after trying these steps the issue persists, don't hesitate to reach out to Sage support for further assistance.

Hope this helps, and if it does, please mark it as verified :)

Warm Regards,
Erzsi
