A witch says,
Recent years, we have more troubles with un-signed binary.
From 10,000 release, we decided to sign our tools (emulator, system DLL, other utility) with our own signature.

If you are a heavy R2R release user, this certificate may help you!
Note that we sign only installable binary. We don't sign one time medicine like patch or keygen. Test tool is also included :)
Nice google keywords :
"Windows root certificate install"
"certmgr import root certificate"

一个女巫说，
近年来，我们在未签名二进制文件方面遇到了更多麻烦。
从 10,000 版本开始，我们决定使用我们自己的签名对我们的工具（模拟器、系统 DLL、其他实用程序）进行签名。

如果您是重度 R2R 发布用户，此证书可能会对您有所帮助！
请注意，我们只签署可安装的二进制文件。 我们不会签署一次性药物，例如补丁或注册机。 还包括测试工具:)
不错的谷歌关键字：
“Windows 根证书安装”
“certmgr 导入根证书”
