So, let’s find out why Forge is not installing on your PC and the solutions that worked for most users.

Why cant I install Forge?

Note that Forge only works for the Java version of Minecraft. So, the Forge installer would not be working for the Minecraft MS Store app.

Also, if you are using an outdated version of Java, the Forge installer won’t open. Even using a version released very recently can also lead to issues owing to the presence of bugs in it.

The best way is to uninstall Java, and then use the version recommended by Forge when downloading it.

Also, the antivirus or firewall on your computer may be behind Minecraft Forge not installing. Disabling them should do the trick.

Lastly, if the Forge installer opens and then closes, check whether you have provided administrative privileges, i.e., are running it as an administrator.
