Unfortunately the database itself was lost when the HDD crashed, but the application makes a backup file to a network share (so it can fill the database again) everytime it is closed. This file can then fill the database again once it is in working order.

I will then setup a Win7 VM installed with SQL 2005 and the application in working order. Upgrade 2005 to 2008r2 (check if the application still works) and then to 2017 (I saw these version jumps can be made). So I can export and import it in the same SQL server version.

I'll let it know what happens
