Troubleshooting

"This app has been blocked for your protection" Error When Trying to Install

If you get the dreadful error above, which means Windows User Account Control blocked your from running/installing the program even if you're running as administrator (in my case, on Windows 10 Enterprise), you should run secpol.msc (Windows Key + R to open the dialog box below). If you don't have secpool.msc because you're running Windows Home and not Enterprise or Professional Editions, you may be able to install it by following THIS TUTORIAL [External Link]

Then, you will open the "Security Options" portrayed below and change "User Account: Run all administrators in Admin Approval Mode" to Disabled:

Next, you'll change "Accounts: Administrator account status" to Enabled (optional, I think the step above is enough, try it first and try the one below only if necessary):

⚠ Restart your computer (even if you didn't enable the administrator account in the image above, because the secpol.msc policies won't be applied before you restart). Then try to install the game again. 😇
