This is the message i am now getting.
Should i now download the newest version?
“It appears you are trying to open a file which has been already accessed by newer version of Manager. Upgrade to the latest version of Manager and try to open this file again.”
It is hard to tell what is happening from here but at a guess
The current version of Manager could not read your old business files as they were too old
The new version may have created a current version (blank) database file
The older v20.9.89 Manager recognises the blank file was created by a newer version of Manager.
So your problem now is probably your application data directory has very old and very new files in it which for which no version of Manager is happy with both.
No that’s the program code directory
The application data directory is where your businesses data is stored. That’s what you want to back up.

I assumed you were using the desktop version of Manager on a windows machine which can work well where only a single user is required
Manager uses two main directories. Their default locations are:
Program code in c:\Users\ < Your Windows login > /Appdata/Roaming/Manager
Business data in c:\Users\ < Your Windows login > /Appdata/Local/Manager
I want to know what is in your business data directory.
Your program code directory in overwritten when you install a different version of Manager, so less relevant. See Install or update desktop edition on Windows | Manager
