If "CONVERSION FAILED" appears in the Select Company window, the recent data conversion didn’t complete successfully.

When you open your company data and the transaction number in the bottom-right corner is zero, the data conversion has failed.  

To continue, click Resolve:

TIP: To access the Resolve button, click the three vertical dots before the Company Name.

• Rollback - click this option to undo the conversion and return to the unconverted data so you can try again
  

  If the conversion fails again, open your data in the earlier version and check your data is in good health. If there are no errors, Reindex and compress your data, then run a clear audit trail to 01/01/1980. Try converting again. If you can't access the earlier version, contact us.

• Preserve - Click this option to preserve the data conversion. The unconverted data saves in a folder next to the ACCDATA folder, named PRECONVERTED_ACCDATA_20XX, where 20XX is the original data version. The full path goes to this folder
  NOTE: If you use the Preserve option, the data conversion is likely to be corrupt. We recommend re-converting your data.

Use a UNC path instead of a mapped drive

Using a UNC path to connect the client computers to the data stored on the server can resolve this issue.  

TIP: If the data file exceeds 2GB and conversion fails, run a Clear Audit Trail. This removes old transactions and reduces the file size.
