This is a fresh install right? You didn't copy it it over your old 2.5 install? Also, which version of java are you using?

Windows explorer (file browser) is not the same as Edge (web browser). Press the windows key + E to open windows explorer.

1.7.10 is also no longer supported here FYI

- Are you running your server from a batch (.BAT) file? If so, check that for the 256M setting. - Open a command window, and type SET and you will get a list of your environment variables. Look through them and see if there are any Java options in there with the 256M setting. If there are, you will need to go into your system settings to remove them. https://winaero.com/blog/how-to-edit-environment-variables-quickly-in-windows-8-1-and-windows-8/

Also just noticed, this is 32-bit java, you're likely to run into memory issues. I'd remove it and install the 64 bit (it will say 64 bit on the HotSpot Client line when you have it)

It is setupDecompWorkspace

The client does not exist within the server, I think your code is reaching across sides.

Post your fml-server-latest.log after your friend tries to connect.

Have you tried deleting and re-creating the profile so it redownloads minecraft? If not I'd give that a try

Try disabling the loading screen as described in the EAQ, I've seen that suggested for this error before. (I just used the forums search box at the top of the page and typed in "pixel format not accelerated".)

1.7.10 is no longer supported, you'll have to update to get help. (also, your pastebin links are broken)

In the launcher, after choosing the profile to launch, go to Launch Options at the top, and the Game Directory shown should contain a logs folder, which will have the fml-client-latest.log in it. There's even a little arrow next to Game Directory that lets you open right to the folder that should have the logs folder. *edit: I tried to paste a screenshot, but evidently I must need to upload it somewhere, but I think you should be ok to find it.

You need to use Java 8, 9 isn't supported

Yeah, but I think it's the size of the minecraft code that requires 64 bit/more memory. @diesieben07 confirm?

Make sure you are using 64 bit java would be my guess

Post logs and specifics

Just to throw this out there, the first log you posted shows minecraft 1.10.2, and this last one you posted shows 1.11.2, so you could very well have some mixup on versions going on.

I guess make sure you have the proper version of animania for the version of forge you're using and/or redownload it and try again. I'm still unsure why the log you posted doesn't have the crash, double check and make sure you're pulling logs/fml-client-latest.log from the proper profile directory (as shown in the launcher)

Weird, I don't even see any errors in there besides missing sounds. I'd still try removing the animania mod and trying it.

You're still not posting your logs/fml-client-latest.log file. But given the error you're posting, Animania is broken, try removing it. Without the log for more information, it's the best advice I've got.

But you probably need to give minecraft more memory in the profile options in the launcher.

Looks like digimobs is broken, try removing it and see what happens

Open a command prompt in the folder where your build.gradle is and type gradlew build *edit: The jar will be in the build/libs/ folder that is in that same folder. This jar file is the one you copy to the mods folder.

I would imagine you could have both versions installed, I don't know how easy it would be swapping back and forth though, you'd either have to change things like the PATH and JAVA_HOME environment variables, or specify full path names to the java(c) executables. This is just a guess, as I haven't bothered with java 9 since I pretty much only use it for tinkering with minecraft.
