Failed to load backup database (database is not valid)

Hi, I am using old version Manager, and suddenly our PC is corrupted and need to reformat again.

And after format, we install new Manager, i think the latest version and show this error after restore backup database manager.

Kindly please help us to solved this issue.

Thank you

Do you know what old version?

If it is very old, search the forum for info on restoring from old versions

You will have to do it in two stages

Out of interest, why are you restoring a backup of a backup of your business?

The two dates in the file/business name refer to backup dates
