Windows Live One Care for Windows Server 2008 R2 and Windows 7

I have been using Windows Live OneCare like forever. It has been used enterprise wide on the desktops and for my demo machines, which is a Vista Business and a Server 2008. I really loved OneCare and to all those that I have recommended it, never called me back!

So here again, for those that are still on third party antivirus suites and trials that most of the time did not worked or worked against the user! "Onecare is also available for  Microsoft Windows XP (Home Edition, Professional, Media Center Edition, or Tablet PC Edition) with Service Pack 2 (SP2) or later, or Windows Vista 32-bit and 64-bit (Home Basic, Home Premium, Business, or Ultimate) operating system (OneCare does not support the Windows XP Professional 64-bit operating system)".


Adding to that, OneCare has also released a support for Windows Servers (for Small Business), and I’m using it in my Server 2008 Demo machines.  Cool huh!

Now here’s the thing, as I have said in my previous posts, I upgraded my laptop to Windows Server 2008 R2 but OneCare did not got installed. But fortunately there is a remedy for that.

So this how to is to Install Windows Live One Care on Windows Server 2008 R2 and for Windows 7!


On the OneCare installer, right click for the context menu and Click Troubleshoot compatibility.








On the Program Compatibility Window, Click Next.

After the Compatibility Runs, This window will appear. Our problem is : The program worked in earlier versions of Windows but won’t install or run now. Click the check box and then Click next.


It was used to run on Vista Versions so we choose Windows Vista, then clicking Next.


After a few moments on resolving issues, the Installer now runs! We now need to press next.

Choose your language, then click next.

On the terms of Use, Accept then click Next.

after accepting the terms, OneCare downloads the rest of the file needed to install. Takes about 15-30 minutes.









While downloading, We should pre-empt the installation that it should run as Windows Vista. To do that, you should navigate to "C:\Program Files (x86)\Microsoft Windows OneCare Live\Staging" and find the "2009-02-16T08-02-49X64mpam-fe.exe" file.

Right click it and go to the compatibilities tab and change all settings for all users. Make sure you set the compatibility mode to Windows Vista.












After the installation has completed make the winss.exe the service app of one care 😀 also in Vista compatibility mode. Its located at "C:\Program Files (x86)\Microsoft Windows OneCare Live"


You may have to reboot to properly install OneCare. And after rebooting?




If you are an existing subscriber, you may need to signup. If not, enjoy the 120 days trial!


The how-to is to make OneCare’s installers (msi’s) and the Service Executable in Vista Compatibility mode.

So there you have it. Windows Live OneCare for your Windows 7 and Windows Server 2008 R2!
