启动不了游戏，应该是电脑问题，可能是哪些问题呢？
不是mod不是客户端不是java不是内存大小这些问题。。应该是电脑本身问题，系统是win7，之前win10也无法启动。

用正版启动器

可能是您的文件损坏，又或者是你电脑的原因哦
您去更换一个客户端试试吧，如果不行，就用【电脑管家】来修复一些文件

你把游戏启动内存设置小一点比如512，再不行就256

您好，请附上crash，不然不能解答的哦

我以前也这样，后来我换了个java就可以了，换java都没用那就换一个整合包试试

整个JAVA、MC重下

重新下载游戏文件，建议使用正版启动器

这是有可能发生的事情
你之前的win10是因为JDK写的部分脚本无法正常运行，MOJANG也曾经发表过这个问题
至于现在你用的win7，  一些mod和win7的32位操作系统也是不兼容的
比如：32位的win7系统就无法运行COFHcore，导致客户端崩盘

请将你的crash发出来= =
不然无法确定错误到底是什么= =

不是mod 不是java 不是客户端 不是内存? 你客户端什么版本?

你可以将内存调到512，然后换成java8,32位的应该就可以了

亲，可以把启动器截图一下吗？

你应该用的是忘却的旋律启动器
下载完客户端启动游戏是正常的，因为mod的原因，接下来我就叫你们怎么弄
xp系统的：首先在空白处点击鼠标右键，出现一个方框。第二个是刷新，别点刷新，点最下面的属性。然后点设置——高级——疑难解答。把硬件加速项移到第三格就行
win7系统的：打开客户端，别点启动，右键开始游戏的图标，然后移到最下面，点击属性。点第二个 “兼容性”。把兼容模式的“以兼容模式运行这个程序”打钩，再把下面一个方框选到 Windows XP（Service Pack 3）就ok了！

为毛我的正版启动器一直offline三天了

可以换一个java8 去官网下载即可
