eM Client won’t start.

Crashing eM Client
1

For the past few days, eM Client has not been starting. Every time I try to launch it, an alert message appears saying that I need to restart the device, which I have obviously tried several times, but the issue still hasn’t been resolved.

Hey @DaveCo

Before you do anything make a Backup: (Menu >Backup)

You can run a repair of the DataBase as it can help.
Eollow these instructions:

WINDOWS

Close eM Client and open a Windows Run window.
You do that by using the Win + R keys on your keyboard.
Paste in this command including the leading "

“C:\Program Files (x86)\eM Client\MailClient.exe” /dbrepair

When that is done, restart eM Client
+++++ +++++ +++++ +++++

MAC

Close eM Client and then “open the Terminal app via either Launchpad or
Utilities” on the Mac. Then Paste and run the following command.

     /Applications/eM\ Client.app/Contents/MacOS/eM\ Client /dbrepair

Then reopen eM Client and see if the issue is gone .

¡Buena suerte!
