Hi everyone,

I recently upgraded a project from 8.0.0 to 8.2.2 for the first time. Everything so far has been going fine. But now when i try to start the project i run into the following error:

```auto
An error occurred while starting the application.
AggregateException: One or more errors occurred. (Database is upgraded to a later version than the current solution, please update your solution to atleast 8.0.0 version of Litium.)

Litium.Accelerator.Mvc.Program.Main(string[] args) in Program.cs
+
                CreateHostBuilder(args).Build().Run();

```

Is there a step that in the upgrade process that i’m missing? It seems weird to me that it says that the database is of a later version, if anything it should be the other way around. Do i need to adjust something in the database going from 8.0.0 to 8.2.2 or is there something i’ve missed adjusting in the project itself?

Thank you in advance!

Litium version: 8.2.2

Did you run the steps detailed here?

If you run the database update command and still get errors, try and reinstall the tool using the instructions on the same page.

I did it shortly after posting here and it worked. Perhaps the error message should be the other way around.

Thank you Nils!
