em client won't start on Windows 10

After the Windows Live was discontinued and the Mail app proved underwhelming, users were in doubt about the next email service client. Lots of third-party solutions were always there and they recently proved to be much better in every sense than the first-party tool. One of those is certainly the US-made eM Client service. It dates back to Windows XP and it’s one of the best choices on Windows 10. However, some users who made this choice were unable to make eM Client working on Windows 10. It just won’t start for some of them.

Luckily, there’s a solution to every problem. So, start with the troubleshooting steps we provided below and we’ll hopefully resolve the problem at hand.

Solutions to fix eM Client issues on Windows 10

  1. Troubleshoot the compatibility
  2. Run the application as an administrator
  3. Set eM Client as the default Email application
  4. Update eM Client
  5. Reinstall eM Client

1: Troubleshoot the compatibility

Let’s start the troubleshooting steps by checking the compatibility issues. Even though the latest iteration of eM Client is natively made for Windows 10, it’s not uncommon for it to get broken. The leads we found in the dedicated forum point towards the compatibility problem.

To avoid this, we encourage you to run the compatibility troubleshooter. Here’s how to do it:

  1. Right-click on the eM Client‘s desktop shortcut and open Properties.
  2. Choose the Compatibility tab.
  3. Click on the Troubleshoot Compatibility and follow the instructions.em client won't start on Windows 10

2: Run the application as an administrator

Another possible reason for the problem might lie in the limitations Windows 10 imposes to third-party email clients. As you already know, there’s the built-in email app which is subpar when compared to some third-party solutions. That’s why we suggest running the app with the administrative permission.

Also, make sure that the app isn’t already working in the background, which might have caused this issue in the first place. Open the Task Manager and kill the eM Client. After that, grant it the administrative permissions and hope for the best.

Here’s how to run eM Client as an administrator on Windows 10:

  1. Right-click on the eM Client‘s desktop shortcut and open Properties.
  2. Choose the Compatibility tab.
  3. Check the “Run this program as an administrator” box and confirm changes.em client won't start on Windows 10

3: Set eM Client as the default Email application

Moving forward, it won’t harm to set the eM Client as the default email app. If you rather use it over the Mail app for Windows 10, than this is a no-brainer. Furthermore, make sure that the app doesn’t start with the system. Some users were able to resolve the problem by starting the app manually instead of allowing it to start with the system automatically.

Here’s how to make eM Client the default email app on Windows 10:

  1. Right-click on Start and open Settings.
  2. Choose Apps.em client won't start on Windows 10
  3. Choose Default apps under the left pane.
  4. Click on the Mail icon.
  5. Select eM Client from the drop-down list.em client won't start on Windows 10

And this is how to disable the application from starting with the system:

  1. Open eM Client.
  2. Click on the Menu, choose Tools and then Settings.em client won't start on Windows 10
  3. Under the General tab, uncheck both “Minimize application to tray” and “Run on system startup” boxes.em client won't start on Windows 10
  4. Save changes and restart your PC.

4: Update eM Client and NET. Framework

Now, the most prolific solution to this problem we’ve bumped into. And that’s the update. Making sure that the eM Client app is up to date is of utmost importance. Lots of affected users were able to resolve the issue with an update which, seemingly, optimized the application. In addition, make sure to download the latest version of NET. Framework, if you already haven’t.

5: Reinstall eM Client

Finally, if you’re still stuck with the same error, consider reinstalling eM Client and installing it again.
