Can't run two versions of Forge?

Currently, I'm running Forge 1.12.2 (with Optifine) and it works great! However, I want to be able to use another version of Forge along with the version I currently have installed. The reason I installed Forge in the first place was because I couldn't load Optifine by itself for some reason, and I still don't understand why. Anyway, is it possible to have two versions of Forge installed at the same time? I've already tried doing this with multiple versions, but to no avail; Forge crashes everytime. When I go back and look in the launch options, those versions of Forge are still there, even though I've deleted the files off of my computer. If there's no way to have two versions installed at the same time, is the any way to guarantee that the other version of Forge will work properly if I can rid of the version I already have installed?

Thanks!

What launcher are you using? Please provide a screenshot.

This is my Forum Signature, I am currently attempting to transform it into a small guide for fixing easier issues using spoiler blocks to keep things tidy.

 

As the most common issue I feel I should put this outside the main bulk:

The only official source for Forge is https://files.minecraftforge.net, and the only site I trust for getting mods is CurseForge.

If you use any site other than these, please take a look at the StopModReposts project and install their browser extension, I would also advise running a virus scan.

 

For players asking for assistance with Forge please expand the spoiler below and read the appropriate section(s) in its/their entirety.

It is possible to install different versions of forge.

You can delete a version of forge by going to the version folder in your Minecraft path and delete the corresponding version.

Are you saying that if I delete my current version of Forge, I should be able to install a different version with no problems?

You should not have to delete any version to install more.

Can you provide logs for the versions that crash, and please verify that the crashing versions are versions you have not removed the files for.

I ran the recommended version of 1.8.9 three times, and this is what I got.

Those are not logs and 1.8.9 is no longer supported due to its age.

If you wish to receive further support please update to a modern version and provide logs (more info in my forum signature).

Well, I've downloaded the installer for 1.13.2 and it's a .jar file, but I can't open it for some reason. I've downloaded the newest version of Forge 1.13.2 a few times and it never opens. I just can't get the .jar files open. Every time I click on the icon the command prompt pops up (I'm running Windows 10) for a brief moment before going away, and nothing happens. Why does it do this? My previous computer had no problems opening .jar files.

Try running the jar with the command prompt and post the output.

It simply says 'The system cannot find the file specified.' I looked up how to run a .jar file and it didn't work at all.

That means you did something wrong.

Try again. Search up how to run a jar in the command prompt.

Having the same problem as David.   I am using Win10 with Winrar (since I do some resource mods).   However this Forge 1.13.2  is driving me insane to get it to work.  I have Java  jre1.8.0-161 and 8.0-211.  I even changed the properties of jar files to open with java; command window then gone in a flash.  

Then tried it as javaw: nothing happens

to javaws: gives this report as Unable to launch the application

Details:

CouldNotLoadArgumentException[ Could not load file/URL specified: E:\Games\Minecraft\MINECRAFT - Core Mod Styles\v1.13.2\Tools\forge-1.13.2-25.0.191-installer.jar]
    at com.sun.javaws.Main.launchApp(Unknown Source)
    at com.sun.javaws.Main.continueInSecureThread(Unknown Source)
    at com.sun.javaws.Main.access$000(Unknown Source)
    at com.sun.javaws.Main$1.run(Unknown Source)
    at java.lang.Thread.run(Unknown Source)
Caused by: java.io.IOException: File too large
    at com.sun.javaws.jnl.LaunchDescFactory.buildDescriptor(Unknown Source)
    ... 5 more

 

So which java app works?   I even ran the look for in java panel and it only just picks up Minecraft Installer program.

I have limited knowledge on this stuff.  I been trying to update to 13.2 since a lot of my favorite mods are now up to 13.2.  I been using the substitute for Forge on 13.2 but now that Forge is out they won't be updating (actually they never updated since their release)

 

I JUST FIXED IT AND INSTALLED still :  if at all can Forge have the easy button for Windows?  since that never gave me any issues

 

 

DAVIDM:

 

okay, what I did was this:

1st:  Move Forge to Desktop

2nd: click on the forge without opening it!

3rd: hit Window Icon on keybroad + X 

4th: Choose Command prompt with Admin

5th Type in                     java -jar (file location*)    then enter

*Location should be at C:\Users\xxxx*\Desktop\forge-1.13.2-25.0.191-installer.jar

**user is the person profile

 

6th: Forge should prop up!

7th: you can move forge back to where you save files

 

Hope this works for you and anyone else!

I didn't have a problem in this thread though...

The OP is @Plugin.

 

I'm glad that you are trying to help others; however, the problem you are encountering is not exactly the same as what the OP is asking help for. In the future, please create a new thread for your problem, as having multiple problems in one thread can cause confusions.
