How to works
What was the extension you were trying to install ?
The attached image does not display the name of the Extension.
If your Make ‘Pro’ trial has expired you will not be able to activate the ‘Advanced Camera Tools’…
Is that the one that’s giving you the message?

The error message needs to be improved in any case. Saying “for some unknown reason” and not stating the offending file are hardly useful!
@Albin Please crop your images down to just the dialogs we need to see. (Those huge images are wasting space on the server.)
