I wanted to upgrade to 9.0.1708.0 (I am already on version 9).
Wanted to make sure I do this properly where I dont lose all my settings, Accounts, etc…
Can I easily upgrade or is it a complete reinstall?
EDIT: Nevermind. After posting this I suddenly got an “Upgrade” pop up in emClient so it is underway!
If it doesn’t officially push the update on your computer normally, you just backup eM Client manually via “Menu / Backup” and the close eM Client once backed up and d/l the latest official release version via the history page and install.
eM Client version history page.
The latest version 9.0.1708 was pushed to all Windows users today.
@Gary
Thanks for the update.

The new version is working great 
I upgraded yesterday to 9.0.1708 (2cfb4a5) and now eM Client will not fully close, in the background is a notice “The application is uninitalizing.” Only by terminating the app session will it close so it can be launched again.
