Error 26 message in Virtual TimeClock

What does error 26 mean?
An error 26 means that the file that you are attempting to open is not a database that can be read by your TimeClock; it is likely a database from a newer version of Virtual TimeClock and is not compatible with the older version you have installed. There are two ways you can get into this situation:

  • Install a newer version of Virtual TimeClock, create a database and then roll back to the older version of the software and attempt to open the newer database.
  • Install an older version of the TimeClock and attempt to open your database from a newer version.

How to resolve the issue.
There are several options for resolving an error 26.

  • Reinstall the newer version of Virtual TimeClock to keep using the database you are attempting to open.
Note: If you are not licensed for the newer version, request a discount code to upgrade.


  • If you wish to continue using the older version of Virtual TimeClock and you have a database backup from that version, you can restore the backup and continue using the time clock.
  • If you do not have a backup of your database, you can start fresh by creating a new database.

If you have any questions about this issue, or need help with your database, contact our technical support team for additional assistance.
