  1. this solution is known to me from a long time ago, but it just doesn’t work for me anymore on Windows 10

    1. Can you specify what exactly are you doing?

      1. well after unlocking my Admin account I login to it. Then i try to uninstal “microsoft office access database engine 2007” then i get error message “This action is only valid for products that are currently installed”, but when i try to install MS Office X64 i get a message to uninstall this particular program. Problem is that I don’t remember installing that program in the first place. I’m using Windows10.
        Also when I try to install or repair this software i get a message that I’m not an admin.

        1. The error that you are getting is just because the Office installation might be messed up on your PC. Log into your regular account and use Revo uninstaller to uninstall Office. You can then reinstall it to see if it works correctly or not. I was going to suggest you to repair office, but it’s not really working for you.

          As for the Access database engine 2007, I guess that it might have installed itself during a Windows update. Don’t worry about it, though.

          1. Thank you for your help, but still nothing worked. So I downloaded trial MS Office 2016 x64 and somehow it worked.

            1. Oh, man! Tough luck. 🙂

  2. hi ,
    I have window 10 dell laptop same problem i am facing even i have logged through administrator account . still am not able to install or delete can you please help me

    1. So, you enabled the actual admin account on your PC as I mentioned in the post, and still you are getting the error?

  3. Hi, I switched to Windows 10 last week. And I also get this message “system administrator has set policies to prevent this installation”. So, I did what you suggested, logged in as the “true administrator”. But the problem remains. I get the exact same message. It is a company-laptop. I’m trying to install some apps I use for training (from Garmin and Polar). Do you have a different suggestion?

    1. It’s quite typical of companies to restrict the usage of their laptops for employees. I guess you can do one thing.

      Search for Local security policy in the start menu search. Open it. Click on Software restrictions policy. Do you see any policies defined there? Your company’s IT people may have set one where you can’t install any unauthorized software on your laptop.

      While the Software restrictions policy is highlighted, look at the right pane. Double-click on Enforcement.

      Select “All users except local administrators” and press . Restart your PC and then try your installation. See if that works.
