AutoCount Payroll restore error: "Expected backup version 1..8. Found 9"

The new PC runs an older Firebird than the server the backup came from.

Updated 2026-10-12 · autocount-payrollrestorefirebird

Symptom. Restoring an AutoCount Payroll backup on a new PC or server fails with Expected backup version 1..8. Found 9.

Cause. The backup was made by a newer Firebird database engine than the one installed on the restoring PC.

Fix.

Log out of Payroll.
Uninstall Firebird on the new PC.
Check the Firebird version on the old server.
Install the same or a newer Firebird version on the new PC — but not 3.0 or later, which AutoCount Payroll does not support.
Restore the backup again.
