Import error, need to download older version

Hi all,

Since almost 2 years that I didn’t use the software, and my *.manager data file was a backup of version 17.4. Now when I try to import the business file into the newest 19.x it shows the error as below. Is it possible to find the old version 17.4? I am so happy to get back. Thanks.

I don’t think is possible to get download other than from old users or @Lubos himself to help you convert it.

What operating system are you using it?

Current version of Manager should be able to read databases at least 5 years back. I think the issue is elsewhere - not in the version. Would you be able to send me the accounting file to ?

I am using Mac OS. @acecombat2 I will then send a copy to @lubos
Thank you for your help.
