Hello everyone. I have another problem with my Windows Vista Home Premium. I am getting tired of this, it is just getting worse. First I noticed that new drivers, such as my new mobile one, would not install. As it used to I tried to make an update using the driver update. For my surprise it could not be installed. I have also been trying to install Windows updates, and none of them is having a successful installation. All of them revert back. Then, when trying to access Device Manager, under System and Maintenance at Control Panel, it denies access and shows the following messages: “is not a valid Win32 application” and “C:\Windows\system32\mmc.exe is not a valid Win32 application” I actually found the mmc.exe file in my C drive. Can someone please help me with this issue? I don’t know what to do anymore. Thanks
