Old version database not recognized by latest download

My main desktop died last week. I was able to retrieve the database but had to download the latest desktop version to install on the new computer which is running Windows 11. My current Manager version is 21.1.12
The latest download tells me the database is not recognized.
I can still open it on my laptop as I installed the program on it a long time ago.
Is there anyway I can import the old database into the current format?

download and install version 20.9.89 from the below link.

make a backup of your data using this version.
then install the latest version.

Hi. Thanks for your assistance.
When I tried to open the database it reported the database had already been opened by a latter version and could no longer be opened by that version.
I then backed up the database on the laptop and using your link managed to change the link to take me to version 20.1.12. I downloaded that version and installed it.
Manager now works with my new computer running Windows 11.
Any ideas on how to update it to the latest version.
Peter

what was your old version number?

20.1.12 or 21.1.12 ? because 20.1.12 is even older than the 20.9.89 i suggested.
