I successfully placed GenP in the C drive. However, this is my host update log.

After running the program, I checked the host file again, and it had been restored to its original state.

I've been having the same issue on the Advanced method Host File updater, keeps saying that on the log. I made sure to change the GenP file path to where GenP is in my Downloads (C Drive) and I made sure the folder and Downloads itself has full admin access on all my admin accounts.

But the updater task works just fine when it uses the backup URLS, so I've kinda just let it be since it still works. Plus since I've now started using Wintrust on Premiere and Photoshop (Acrobat blocks popups great just patching with GenP), I've not really used the hosts file anymore anyway.

    Your own GenP.exe ran correctly on your system, but it wasn’t able to download the blocklist from the server it normally connects to.

    Because the blocklist couldn’t be retrieved, the script marked GenP’s output as invalid and then tried the backup URLs.

    Those backup sources also failed to load, which means your network or ISP is blocking all of the domains used for fetching the updated hosts entries.

    Since no valid blocklist could be retrieved from any source, the script automatically restored your hosts file to the previous backup to prevent writing an empty or incomplete file.

    That’s why the hosts file returned to its original state.

    To fix this, make sure your network can access the domains used by GenP and the fallback URLs.

    Using a VPN or changing your DNS (for example to Cloudflare 1.1.1.1 or Google 8.8.8.8) usually resolves the issue.

    Security software such as antivirus HTTPS filtering can also cause this problem, so temporarily disabling that may help as well.

    The advanced script works perfectly as long as GenP can reach the latest domain list, or, if that fails, any of the backup URLs remain accessible on your network or through your ISP.

    This situation is also mentioned in the Advanced Method section of the GenP guides, which explains the connection requirements and what to check if the script cannot retrieve the blocklist.
