That version has not been supported for many years. You are the only one who can fix this issue.

Start by backing up your application data folder. That’s where all your businesses data is stored. The files end in .manager, and are probably located here  
`C:\Users\ < your windows login name > \AppData\Local\Manager`  
Save several copies now.

After which to update from such an old version a two step process will be required.

First install this old version the open you businesses as described here [Manager does not want to import my old database - #2 by Patch](https://forum.manager.io/t/manager-does-not-want-to-import-my-old-database/34082/2)

Then install the current version
