beyond compare 4.2.9桌面右键集成的问题修复
安装后，发现在WIN64时，注册表中注册的DLL库有问题
出错处：
1 [HKEY_CLASSES_ROOT\CLSID\{57FA2D12-D22D-490A-805A-5CB48E84F12A}\InProcServer32] 2 @="D:\\05.Tools\\BeyondCompare4.2.9\\BCShellEx.dll" 3 "ThreadingModel"="Apartment" 修改为：
1 [HKEY_CLASSES_ROOT\CLSID\{57FA2D12-D22D-490A-805A-5CB48E84F12A}\InProcServer32]2 @="D:\\05.Tools\\BeyondCompare4.2.9\\BCShellEx64.dll"3 "ThreadingModel"="Apartment" 如果还不行，注意去这儿删除相应的{57FA2D12-D22D-490A-805A-5CB48E84F12A}信息
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Shell Extensions\Cached]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Shell Extensions\Cached]
修复右键的完整的注册表项见下，注意修改为你电脑上BC4的安装位置（目录需要双斜杠）。
