I am running microsoft 10, java 1.8.0_271, and I am trying to install forge-1.16.4-35.1.7-installer.jar.

It says I don't have permission to access the file. I am the administrator on this PC.

I have run 1.16.4 on minecraft, I have tried  jarfix, I have tried uninstalling and reinstalling Java. I also just tried to install forge-1.16.4-35.1.0 and it gave me the same message.

Misspelled jar fix and added more info

Here are my attempts to install the loader. 

I am pretty new to all of this. I even tried to install it from the desktop and got the same message. I was just guessing where it needed to be. Thank you I will do it like you said.🙂

 

Okay, I have uninstalled Java 32-bit and Java 64-bit. I have reinstalled Java 64-bit, I have run the Jarfix. I have uninstalled and reinstalled Minecraft and started a game for MC 1.16.4. I am still getting the same message.

I also tried to run from the command prompt

I can, I downloaded another forge installer for 12.2.2, which is a game I had played previously and had the Forge Jar file for. I have it installed and was able to start a game with it.

forge-1.12.2-14.23.5.2838-installer-win.exe is the file I downloaded from the Forge website. It is an .exe file and I clicked run and it ran. When did Forge start using .jar files for installing files? Then I started my Minecraft  the forge was loaded so I created a new game with the Forge profile.  So I am thinking that the .jar files are working. I have even added some mods and they are working as well. I just noticed when they stopped doing the windows .exe installer files.
