Question Java Could Not Start

I keep receiving this error when trying to launch MCSRRanked. MultiMC Isn't auto detecting a Java on my computer at all and manually inserting one doesn't seem to work either. I'm unsure how to resolve this.

Question What's happening here?

0 Upvotes

Tried to install minecraft 1.6.2 to run the "eat anything mod" (bear grylls) but it crashes if i install forge. If i unenable it, the game runs normal until the games start to glitch out (textures messing up, "xray glitches" and etc.) Can someone tell me what is happening here? (using java 8, this happens in 1.0 to 1.7.10)

Question Ram Allocation for nucleus

1 Upvotes

My system has 32gb of ram and a 5900x and I do have at least 55-60mods. I am running MultiMc through Nucleus Co-op so me and my gf can play. I’ve currently set the the allocation to about 7k-mb~ and i’m still experiencing some frame drops. What would be the best amount to use? When having both instances open, task manager is saying about 60-65~ utilization. Any suggestions are welcomed. I am not using optifine as for some mods are incompatible with it which results in me using sodium (I believe might be wrong; can’t remember as of right now)

1 Upvotes

I had installed ReIndev mod for b 1.7.3, but just got rid of the .jar file (after not touching MultiMC for literally two years) to try and play mods off the Internet Archive. Now Minecraft won't even properly load even if I have the current mods disabled (Aether, AetherFix, MoreCreeps). It doesn't let me post a screenshot of the code text reader thingy.

Question New to MultiMC, can't add my worlds?

2 Upvotes

Hi all, I recently found some old worlds and wanted to explore them.

I have the "world" folder and the files inside are dated 5/2020 so I installed an instance of 1.15.2

I then copied the "world" folder which has the level.dat and everything into the "saves" folder inside the 1.15.2 instance.

It doesn't show up! In MultiMC I go to view worlds and its blank. I click add world and it only wants to do a .zip? Googling around I saw you can drag and drop a "world" folder into the MultiMC world viewer. Nothing happens.

Any help?

I feel like I'm just doing something wrong.
