And windows doesn't have built in Ransomware either - I was tired when I wrote that last night and missed out the word protection. Windows has built in Ransomware protection that if it is turned on, requires you to specify which programs are allowed to run on your computer. But you would know that if you read my reply to the person who started the thread.
The person who started this thread asked a question and I made two suggestions in my first post in the thread. One of them was to check if the Ransomware protection is turned on. The other was to ask if they had installed AS by right-clicking on it and choosing Run as Administrator.
I don't have any recent experience of Norton (shudder) so if Norton is blocking it then I can't help you with that. Ancestral Sources has been downloaded over 35,000 times over the last decade or so and I pay £100 each year to purchase a code signing certificate to prove it is legitimate which requires very long and frustrating vetting processes each time but despite all that your computer has decided I'm not to be trusted. Very frustrating. Its things like this that make me ask myself why I bother.
