- Make your way to the Virus & Threat Protection in Windows Security and then head to the Ransomware Protection menu.
- Here, click on “Allow an app through Controlled folder access” and then click on “Add an allowed app”. Here browse through the pop-up and then head to the game’s folder.
- Once in look for TheFirstDescendant.exe. Click on it and then select Open.
- Next, click on “Add an allowed app” again, head to the games folder once more, and then click on EACLaunch.exe. Open it, to add it to the firewall exception.
- You will need to repeat the process a final time, but this time you will need to go to the following folder directory: M1->Binaries->Win64. Look for the M1-Win64-Shipping.exe, Open it to add it to the Windows Firewall.
Once done, you will not be having any firewall-related issues with The First Descendant.
