Reinstall eM-client without data loss

After reinstalling Windows 10 I have to reinstall all programs. All data is still available. How can I reinstall the eM client and access the latest mails? Where can I find all needed files from eM-Client?

First, you can download and install the latest version of eM Client from the Release History.

Then if you have a C:\Windows.old folder, with eM Client closed, copy the eM Client directory from C:\Windows.old\Users_username_\AppData\Roaming\ to C:\Users_username_\AppData\Roaming.

Restart eM Client and all your data and settings will be there.
