[FIXED! finally] I put a 1.12 forge in the launcher and now it wont work...

[ThatGuyThomas 0]

Can anybody please help me on this? This glitch has been happining to me for a very long time, and I just want to play minecraft with minecraft 1.12 forge. Also, thank you for the people who have been doing so. I really want to play.

Okay, so at this point I'm just gonna take matters into my own hands and fix it myself, because it been over a week since I played. Also, if there is any suggestions that anybodyy can give me, put it in the reply section and I might try that without questioning it! Thank you, and have a nice Summer Vacation.

 

P.S. I will also note you guys on when I get this fixed! = )

Apperently, everytime I try to play minecraft with forge 1.12 it just either crashes or it just never loads. So I un-extracted every mod I had in forge 1.12 but it is still not working. I also deleted proof of the extracted mod in the fml section thing and made a seperate game directory for it but it is still not doing anything.  Can you please get any suggestions of help on why this is happening, I havent played minecraft in general for I think 2 weeks now.

To uninstall Minecraft (or any other program) on Windows 10, open the Start menu, type in "Apps and Features" and click on Apps & Features in the search results. Find Minecraft in the list, click on it and click Uninstall.

 

To install Minecraft, go to minecraft.net, log in and then download and run the installer.

 

To install Forge, go to files.minecraftforge.net and download and run the installer for the version you want.

Your account won't be affected, that's controlled by Mojang and not stored on your computer.

 

Any local data (e.g. saves) will likely be deleted, so back up anything you want to keep (i.e. copy it to a directory outside of the .minecraftdirectory).

Probably, yes. If you want to keep them, back them up before uninstalling and then copy them back to the original locations after reinstalling.

Okay, so instead of trying that, I'm gonna try deleting every mod I had in the forge mod folder, but if that doesnt work, Ii may have to download the other forge 1.12 or even a 1.11 one or something. If none of those work, then I MAY have to uninstall and install my Minecraft. Thank you for your help, and I will tell you when its working agian.

Okay, so good news and bad news!

Good news: I finally got forge 1.12 to work!!! :D

Bad news: all of my mods in it are gone...

So, what I think I'm gonna do is re download all of them then put it in my mods folder WITHOUT extracting them next time.

This thread glitch is still not finished or fixed, so if there are any updates with it, I will let you guys know.

Thank you to EVERYONE who participated in helping me out with this, Happy Summer!! :)

[ThatGuyThomas 0]

Okay, so what I did was instead of playing the actual forge 1.12 I used the regular vanilla miencraft 1.12 an, strangley, it still had forge in it. But atleast it worked from there. But, I re-downloaded all the mods I had (which was basically 1 xD) and I put them in the mods folder WITHOUT extracting them and now it isnt working. I think I messed it up somehow but I dont know since people were telling me the reason it wasnt working was because I had the mod EXTRACTED but it is no longer extracted from WinRAR to a folder but it is yet still not working. But I also know that the mod I have is the problem since when I dont have the mod inside the mods folder, it works perfectly fine. So, can somebody please tell me a way for me to have the mod AND play minecraft forge 1.12 with it? Thank you. MOD LINK: https://minecraft.curseforge.com/projects/quark (Its called The Quark Mod) Please tell me what is wrong with it.
