You have several issues as a result of being, literally, thousands of versions behind.
The first is that the current version no longer includes the conversion script to update to the present SQLite database structure. So you are going to have to update to a somewhat older version first, which will convert your database. Then you will be able to update to the current version of Manager. See this post from the developer: Business database not valid, desktop version on Windows 10 - #2 by lubos
The second is that must surely be more to the error message than you posted. Can you post a screen shot of the entire message?
The third is that you are going to need to find and isolate your business data file in wherever you have moved your application data folder. You will need to know where this file is in order to import it to a functional location. See this Guide for background: Manage application data folder contents | Manager.
