Forge 1.8.9 compatibility with forge 1.14.4+

[d4nvol]

I need 2 forge versions to be installed in my minecraft, forge 1.8.9 and something newer. But when i install forge 1.8.9 and then 1.14.4(or 1.15.2), version 1.8.9 doesnt work. Looks like when i install 1.14.4 version of forge, it replaces a lot of files in 'libraries' folder, which are necessary for version 1.8.9 to work. Version 1.8.9 even disappears from the list of versions in Minecraft launcher.

 

Is there a way to make forge versions 1.8.9 and 1.14.4 work together?

 

Here's how I installed these versions:

1) First I fully reinstalled Minecraft Launcher and then installed forge 1.8.9(tryed latest and recomended versions)

At this moment forge 1.8.9 work properly

 

2) Then I installed forge 1.14.4(also tryed forge 1.15.2). Now 1.14.4 work properly, but 1.8.9 just disappears from the list

You should create a separate Launcher Profile for each version.

Click on the "New" button on the top of the "Installations" page to create a new Launcher Profile.

Somehow i added both versions in the list, but 1.8.9 still not work.

1.14.4 works, but 1.8.9 not
