Innosetup 脚本写注册表实现自定义协议（Url Protocol）

 [Registry]
Root: HKCR; SubKey: NGIE; ValueData: "NGIE"; ValueType: string; Flags: CreateValueIfDoesntExist UninsDeleteKey;
Root: HKCR; SubKey: NGIE; ValueName: "URL Protocol";ValueData:{app}NGIE.exe; Flags: CreateValueIfDoesntExist; ValueType: string;
Root: HKCR; SubKey: NGIEshellopencommand; ValueData: """{app}NGIE.exe"" ""%1"""; Flags: CreateValueIfDoesntExist; ValueType: string;

注意command项一定要加引号把路径包起来，否则不起效果
