Error: "Unable to open the company file" during conversion

Summary

How to resolve the error: "Unable to open the company file" during or at the end of a Sage 50 Accounting data file conversion.

Resolution

▼ Check the file attributes
  1. Go to the data file location.
  2. Right-click the SAJ folder and select Properties.
  3. Select the Read-Only and Hidden checkboxes.
  4. Click Apply then uncheck the Read-Only and Hidden boxes.
  5. Click Apply again.
  6. Click Apply the changes to all subfolders in the SAJ folder.
  7. Right-click the SAI file and repeat the steps above.
  8. Verify that you can convert the data file.
▼ Run the program as an administrator
  1. Run Sage 50 as administrator.
  2. Verify that you can convert the data file.
▼ Restore from backup
  1. Find and restore a backup file created locally before the first conversion attempt.
  2. Save the backup as a new file. Don't overwrite the old one.
  3. Locate the new data file and open the SAJ folder and make sure there’s no conversion log.
    • Conversion logs are time-stamped text files created when a conversion fails
      • For example, 2017-06-28-16-20-55.txt - this file failed to convert at 2017 June 28 4pm
    • Find a backup before this date and restore it
▼ Move the file to the local computer

 

Ensure all files are on a local drive when converting to a new version.

  1. If the file is on a network, copy the file locally.
  2. After conversion, copy the file back to the network.
▼ Check the SAJ folder
  1. Open the SAJ folder.
  2. Check for duplicate file names that contain:
    • ibdata1 (Copie de Joe confliCt 2012-09-27) ibdata1 (Joe's conflicted copy 2013-01-09)
    • accounts (1).frm, simplygroupmembership (2).frm, tbgtah01-1.frm or tbgtah01-2.frm;
    • Verify the simply and mysql folder doesn’t have extra files or folders as well
  3. Make a copy of the SAJ.
  4. Remove all duplicates and extra files.
  5. Verify that you can convert the data file.
▼ Disable the antivirus, firewall, and real-time scanners
  1. Disable the antivirus.
    • If you have more than one antivirus software, uninstall them and leave only one, and disable it
  2. Turn off the firewall and real-time scanning.
    • If you use McAfee, turn off both real-time scanning and the firewall
  3. If your computer is using any auto backup software to backup company data files, disable it.
  4. Right-click the Sage 50 icon and Run as administrator.
  5. Start the conversion again.
  6. After file conversion, re-enable any security software.
