can't install sorter and mac os in use

When I am asked whether I want to replace the beta 1 version that is in my application folder, I click replace. However, I get the error message that the operation could not be completed because the Devonthink sorter is in use. When I click on OK, I then get the error message that the operation could not be completed because the macOS is in use.

I also am now unable to open devonthink.

I appreciate the help.

Delete the earlier beta version and empty the Trash.

Now install the new version in your Applications folder.

It works. You have made a believer out of me! :slight_smile:
