Hi Carolyn Duncan ,

Thanks for reaching out. Did you ever find an answer to the issue with opening the 2024 file? It sounds like you're encountering an error stating that your company file is being used by another application.

Based on the information you've provided and referencing our article on updating to the newest version and troubleshooting data conversion issues, there are several possible solutions:

**Option 1**: Verify path location
- Ensure the files are on a local drive during conversion.
- If the file is on a network, copy it locally, and after conversion, copy it back to the network.
- Ensure the file path is no longer than 284 characters.

**Option 2**: Test if the sample company opens
- Try opening the sample company. If it doesn't open, there are steps mentioned in the article.

**Option 3**: Check the SAJ folder for duplicate files
- Look in the .SAJ folder for any duplicate file names like ibdata1 or accounts (1).frm.

**Option 4**: Restore a Backup
- Restore a .CAB backup file locally. It's recommended to restore to a new .SAI file and .SAJ folder.

**Option 5**: Adjust Anti-virus and Scanners
- Disable any antivirus or security software temporarily.
- Check Windows Event Viewer logs and ensure there aren't any MySQL related warnings.

**Option 6**: VPNs Running
- Disable any VPNs and try again.

**Option 7**: Check the errorlog.txt file
- If the errorlog.txt file at the data file location shows anomalies, the file might be corrupted.

**Option 8**: Verify file attributes
- Ensure the company file (SAJ and SAI) isn't set to read-only or hidden.

**Option 9**: Ensure User Account Control is enabled.

**Option 10**: Check Advanced Database Check log
- Run an Advanced Database Check in the previous Sage 50 version and refer to the mentioned article.

If after trying these options the problem persists, it might be a good idea to call our Customer Support at 1-888-522-2722 for further assistance.

Warm Regards,
Erzsi.
