I don’t have the solution but I can say that it can install on win 11. I had the same prompts as well as more. It was flagged by the browser on download (Edge) as well as when I went to open the file. I also use malwarebytes and that flagged it as well. After all that, it did install fine thought, even with all security features turned on. Including UAC.
Yeah, also Win11 here, also running with no issues. I do leave the ransomware projection on, but I’m pretty aggressive about granting permissions to blocked apps. Do you see VCV getting blocked if you go to windows security / Virus & threat protection / Protection history? If so, click on an entry and allow it.
