I've just updated to B1776 and found that a pop up Microsoft Edge error appears when starting CMO. Please see the attached screenshot.

Try adding the WebView\EBWebView folder manually. That worked for me.

Indeed.

Create a C:\Temp folder it is does not exist.

Edit the file Command.ini, located in the config folder of the game. For that you may use Notepad.

Add this line below the Tacview line.

CustomFolder_WebviewCache = C:\Temp

Save and close Command.ini.

Now you should be able to run CMO without that error.

Note that if you are jumping from B1676 to B1776, you may get another error.

To avoid that extract this patch first in CMO folder. After this extract B1776 patch.

Thanks Mark. This also worked for me.

Nikel, thanks also for your advice. I'll try this if I encounter any other issues.
