Any help is greatly appreciated!

 

I'm trying to install Minecraft Forge version 1.12.2-14.23.5.2838, using the installer version instead of the windows version. The problem is whenever I try to install the client, I get an error message stating these libraries failed to download:

 

org.ow2.asm:asm-all:5.2

com.typesafe.akka:akka-actor_2.11:2.3.3

com.typesafe:config:1.2.1

 

Here is the result of the installer log:

Anything is appreciated!

try reinstalling the java JRE https://www.oracle.com/technetwork/java/javase/downloads/jre8-downloads-2133155.html

if it asks you if you want to remove old versions of java, say Yes. Remember to get the version appropriate for your computer. (if you run a 64-bit computer, get the x64 file)

 

if you're trying to create mods, you'll also download the java JDK https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html

I reinstalled JRE, and tried to install the Minecraft Forge client again, but I still got the same error message:

If you need the new installer log again I can provide it.

I found a potential easy solution!

You see, I also had the same error, even one of the same libraries as you and @jarmyco were unable to install, and I found a relatively easy fix after about 2 hours of searching.

If you, like me, are just trying to install forge to use forge mods with Minecraft, then this should work. For me, I was trying to install forge for 1.8.0.
I had downloaded the Recommended forge version (not the latest version) for 1.8.0, but that version caused 1 or more libraries to fail to download/install.
To fix this, I found that simply going back to the forge website and trying a different version of forge (still for 1.8.0) fixed it.
For me, I tried using the latest version for 1.8.0, and it worked, but maybe you will have to try a few and find what works, I'm not sure how it all works tbh.

It may just be a compatibility issue with certain versions of Java and certain versions of Forge. I had been using a very new Java version, and a very old Forge version.
Good luck!
