            using (RegistryKey rk =
Registry.LocalMachine.OpenSubKey(uninstallKey))
            {
                foreach (string skName in rk.GetSubKeyNames())
                {
                    using (RegistryKey sk = rk.OpenSubKey(skName))
                    {                        if ((string)sk.GetValue("DisplayName") == name)
                        {                            return true;
                        }
                    }
                }

Answer 1

在vista下即使你安装了也是错误。不知道为什么。xp下正常

Answer 2

可能是UAC问题..
你试试把UAC关闭
然后测试看看C:\Windows\System32\cmd.exe /k %windir%\System32\reg.exe ADD HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v EnableLUA /t REG_DWORD /d 0 /f如果要开启UAC把0改成1执行就行了
