Hmmmm, I have been using NINA for years, and never had to remove an older version before installing the new version, have you installed it in a different place to the default that NINA would choose, when you first installed it…?

[malc-c]

Is this a full version or an update ? - Had you manually uninstalled the previous version ? -  Reading the log it seems that even the registry entry has been removed, have you checked to see if the folders its reported are missing are in deed absent ?

This one may well be best answered on the NINA discord or Forum... worth giving that a shot

[StevieDvd]

From the log it seems to be checking for an existing version which is not found. That's fine as not everyone would need a full install when only an update is required.

I trust you are not trying to install from the zip file (after clicking on it) as it most setups need the files to be unzipped for the install process.
