not_support

Error message

不支持的文件：名称 {editor.FileName} 版本 {editor.FileVersion}！

What it means

The file's SHA1 matched neither SHA1Before nor SHA1After, its version matched no ModifyInfo, and no CommonModifyInfo (feature/signature) applies for the file's version range. AppModifier throws BusinessException('not_support') with the file name and version.

Solutions

  1. Update RevokeMsgPatcher to the latest release for newer patch data.
  2. Check the supported version list; downgrade the target app to a supported version if needed.
  3. Confirm the correct install path and that the expected DLL is being targeted.
Defensive patterns

Strategy: try-catch

Type guard

static bool IsBusinessException(Exception e, string code) => e is BusinessException b && b.ErrorCode == code;

static bool IsNotSupported(Exception e) => IsBusinessException(e, "not_support");

Try / catch

try
{
    modifier.ValidateAndFindModifyInfo(categories);
}
catch (BusinessException ex) when (ex.ErrorCode == "not_support")
{
    MessageBox.Show($"不支持的文件版本，请更新本程序或使用受支持的版本。\n{ex.Message}");
}

Prevention

When it happens

Trigger: The target DLL is a version for which the patcher has no data at all: neither a precise SHA1 entry nor a signature-based entry in range.

Common situations: The app updated to an unsupported version; a wrong/unexpected file was targeted; patch.json is out of date.
