I’m glad to hear that, in my case the updates were installed to the former path a. (ProgramData).
When I used the Windows context menu Open file location feature on the shortcut, it led me to the original installation directory duplicati-2.0.6.3_beta_2021-06-17.
My first reaction after realizing there is an “old” installation was to delete the shortcut pointing to it to avoid further mess by accidental execution of it, so that mystery might stay unresolved.
Verify files was successful with no warnings or errors, so I’m confident that everything is fine. Thank you for your support!
