Is this possible? All I get are errors:
Running the WebBrowserSettings action id: c1646380-ac5a-4c36-ae08-3d9692d91f2f action group id: 180fb664-4c92-4ce4-8abf-e54baf363ae0 Object reference not set to an instance of an object.

I want to close Chromium and start CEF in the middle of the template.
I added action Run without browser and then started CEF, but no success. Even when i press Reload nothing happens. Still same error to start CEF browser.
I have to restart PM to run CEF after Chrome.

Do you use profile-folders with browser instances?
I guess it's not enough to run instance without browser to unbound profile-folder in PM.
you should run Chromium instance without profile-folder, then switch to CEF.

Still not clear what goes wrong... need more details about it
please make full diagnostic with detailed logs enabled after CEF not started and send it via tickets
Also attach screenshots of action properties - Run Chromimum instance and Run CEF instance.

If you don't use profile-folders in a project in PM, does CEF instance run successfully after Chromium instance?

This problem is fixed in 7.7.9.0 version. Test build is already available.

Lets move to new thread if this is not related, but right now I can still see its not really possible to run in zenno after you edit in PM.

What i do is, run template and then after running i try to Run instance without a browser. But this still does not help, as you see in the image. Basically, only closing Project maker helps to unbind profile folder. This is from the latest version 7.11

Same is if i work only in PM, I end my template and wanna rename profile folder. But I can't really do that, as there is still this same error.

To unbind profile-folder in PM, you should run instance with browser without folder. I think it works like this.
