The attached video was made on a clean Windows 10 virtual machine and the only security/antivirus/firewall software installed is that installed by Microsoft Windows.

Some common problems encountered when downloading the installer from the CE website.

1. You must stay connected to the internet when running the installer, otherwise installation cannot complete.

2. If you use a VPN or proxy, you may need to temporarily disable them.

3. Windows cannot access the specified device, path, or file.
You may not have the appropriate permission to access the item.
   If you have installed any third party security/firewall software, you may have to temporarily disable/uninstall it (if you use Avast antivirus/firewall, see How to temporarily disable Avast Antivirus and Firewall #2104).

4. If you still can't download the installer from the CE website, it could be due to your service provider blocking it.
   You may have to disable your PiHole ad blocker if you use one, or even your browser's ad blocker (see this)
   You can also try downloading the installer for the latest release from the repo here.
   You can even try downloading to a mobile device and transferring to the PC.

Issues you may encounter when try to run CE after successfully downloading and installing it.

1. There are some programs/games that will write registry entries that can block CE from running, and you may see an error message like…

   'C:\Program Files\Cheat Engine 7.4\Cheat Engine.exe'.
   Make Sure you typed the name correctly, and then try again...

   Running windowsrepair.exe from inside the CE installation directory might fix this.

2. ANTI-CHEAT PROGRAMS!!!
   If CE doesn't run at all after installation, it may be because you have installed a game like Minecraft or some other game that installs an anti-cheat program, such as Badlion or Vanguard. If that is the case, you will have to disable/remove the anti-cheat (read this on how to remove Badlion).
