Can't open a .cer file?

When you double-click a file to open it, Windows examines the filename extension. If Windows recognizes the filename extension, it opens the file in the program that is associated with that filename extension. When Windows does not recognize an extension, you receive the following message:

Select an app to open this .cer file

To set the .cer file association in Windows 11, you can follow these steps

  3. Scroll down and click on the Default apps option.

  6. Click on the current default app listed under the category. A list of available apps will appear.
