I already downloaded the requested 9.2.1735 version and moved it in different folders. Uninstalling eM Client is also not working because it throws up the same error. Same when trying to install the latest version manually.
Both your images are difficult to read, however, the lower image says
that your installation package is not valid.
I don’t know exactly what you have been doing so I suggest you delete
the 9.2.1735 installation file.
Ln case it is requested download and place it on your desktop:
It always asks me for the v9.2.1735 package which was the latest update that failed. Before that, I had never issues with updating em. I am using em for 2-3 years.
