如何检测PC上是否安装了Microsoft ActiveSync

Question

检测PC是否安装了Microsoft ActiveSync的最佳/最可靠的方法是什么？我的PC程序使用RAPI从设备中获取文件,如果没有安装,则会出现无法找到RAPI.dll的错误.

/// <summary>

/// <param name="syncVersion">The version of the synchronization tool installed.</param>
/// <returns>True: Either ActiveSync or Windows Mobile Device Center is

private static bool isActiveSyncInstalled(out Version syncVersion)
{
            using (RegistryKey reg = 
                Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows CE Services"))
            {
                if (reg == null)
                {
                    syncVersion = null;
                    return false;
                }

                int majorVersion = (int)reg.GetValue("MajorVersion", 0);
                int minorVersion = (int)reg.GetValue("MinorVersion", 0);
                int buildNumber = (int)reg.GetValue("BuildNumber", 0);

                syncVersion = new Version(majorVersion, minorVersion, buildNumber);
            }
            return true;
}
