Dear all, this is just a quick guide, but maybe helpful for some of you!
I had this behaviour with the latest release from yesterdays ISO, to patch to the latest release…
After mounting the ISO and click on Setup.exe I received the following error:
Unable to run the installer because files from this ISO are blocked for security reasons. Use the “Unblock” option in the file properties to proceed.

It’s an easy step, but keep in mind, this you have to do on the ISO file itself, not on the Setup.exe file 😉
So right-click on the ISO, and choose Unblock under Security. Hit OK/Apply and have fun, while applying your urgent updates!

Take care, stay up2date and have a great weekend!
