Hi @fredimagine , in this case judging by the screenshot itself you still might have Enscape 3.5.6 installed? Is there any reason for that, otherwise do you perhaps have the chance to generally upgrade to Enscape 4? You can always acquire our latest release here.
If you experience (or have experienced) any installation problems, with generally getting Enscape 4.0.2.11 installed properly, please also ideally check out this prior post of mine here:
After you have installed Enscape 4, and this message is still occurring nonetheless, please also submit a dedicated support report as detailed here, which additionally connects you with our dedicated technical support team right away for further troubleshooting.
