补丁安装失败，原因：无对应的文件修改器

Error message

补丁安装失败，原因：无对应的文件修改器

What it means

AppModifier.Patch() throws a plain Exception if editors.Count == 0. That means InitEditors was never run, returned false, or no TargetInfo matched the installed app's version range, so no file editors exist to patch.

Solutions

1. Always call InitEditors(installPath) and check its bool return before Patch().
2. Ensure config.FileTargetInfos has entries whose StartVersion/EndVersion range matches the installed app version.
3. Abort the flow with a user message when InitEditors returns false.

Example fix

// before
modifier.InitEditors(installPath);
modifier.Patch(); // throws if editors empty

// after
if (!modifier.InitEditors(installPath))
{
    // InitEditors already showed a MessageBox; abort.
    return;
}
modifier.ValidateAndFindModifyInfo(categories);
modifier.Patch();

if (!modifier.InitEditors(installPath))
{
    // InitEditors already showed '当前版本没有对应的文件修改信息...'.
    return;
}
modifier.ValidateAndFindModifyInfo(categories);
modifier.Patch();

When it happens

Trigger: Calling Patch() before InitEditors(installPath) + ValidateAndFindModifyInfo(...); or InitEditors returned false (showing '当前版本没有对应的文件修改信息...') and the caller still proceeded to Patch().

Common situations: Orchestration code skipped InitEditors or ignored its bool return value; the app version is outside every TargetInfo's version range.
