导入MultiMC

Windows

SmartScreen blocks the installer

错误: Windows protected your PC
01

Confirm the source

下载 from the official Prism Launcher 发行页 — not a repackaged mirror.

02

Open More info

Expand the SmartScreen dialog so Run anyway becomes visible.

03

Continue only if trusted

Choose Run anyway, then finish setup into a clean install folder.

已修复: Reputation warnings fade as more users run the same unsigned build.

Windows

Missing MSVCP140.dll

错误: The program can't start because MSVCP140.dll is missing
01

Install VC++ Redistributable

为您的 Windows 版本安装最新的 Microsoft Visual C++ Redistributable (x64)。

02

Reboot if prompted

某些系统需要重新启动才能更新 DLL 路径。

03

Launch again

从“开始”菜单或桌面快捷方式启动 Prism Launcher。

检查: Use the official Microsoft redistributable, not a third-party DLL drop-in.

Runtime

Pick the right Java per instance

01

Open instance settings

Select the instance, then open Settings — changes apply only inside that boundary.

02

指定 Java 路径

指向与 Minecraft 版本匹配的 JDK 或 JRE(对于现代包,通常为 Java 17 或 21)。

03

Set memory

Raise max memory for large packs, but leave headroom for the OS — per instance, not globally.

已修复: A wrong global Java is a common cause of crash loops. Scoped Java fixes the loop without touching other setups.

迁移

导入 from MultiMC

01

Export 或 copy the instance

在移动之前,请保持 MultiMC 实例文件夹完好无损。

02

Use Prism import

在添加实例中选择MultiMC/Prism兼容的导入路径。

03

Verify Java and accounts

导入后重新检查loader版本、Java路径、Microsoft账号。

检查: Worlds and mods stay under the new instance directory — boundaries preserved.

游戏

Mods not loading

错误: 游戏以原版启动或在模组初始化时崩溃
01

Confirm loader match

Forge模组需要Forge; Fabric mods 需要Fabric。混合罐子会安静或大声地失败。

02

Match Minecraft version

如果没有兼容的版本,1.20.1 mod 将无法在 1.21 实例上运行。

03

Read the log

打开实例日志并删除第一个缺少的依赖项或损坏的 jar。

已修复: Clean packs from Modrinth 或 CurseForge reduce version drift inside one instance wall.

安全 tooling

杀毒软件将二进制文件隔离

01

Restore from quarantine

如果您的 AV 删除了 Prism.exe,请从隔离列表中恢复它。

02

添加窄范围排除

仅排除您信任的 Prism 安装文件夹,而不是整个驱动器。

03

Re-verify checksums

在保留排除之前,比较发行说明中的​​哈希值。

检查: Heuristic engines sometimes flag game launchers. 源码 review lives on the 信任 page.
