Diablo 3: Fix “Below Minimum Requirements” Error

When trying to install Diablo 3 for the PC, a lot of people are getting a “Below Minimum Requirements” error when they try to install the game, even though they feel that they meet the minimum requirements listed on Battle.net.

The issue that most people are having though (which it doesn’t really specify in the error) isn’t necessarily that you’re below the actual minimum requirements, but that your operating system isn’t up to date.

If you look closely, the minimum requirements state that you need to have the latest service packs for Windows XP, Windows Vista, or Windows 7.

The latest service pack for each are:

Windows 7 – Service Pack 1
Windows Vista – Service Pack 2
Windows XP – Service Pack 3

Go to the Windows Service Pack Center to download the latest service pack for all three versions of Windows.

If that doesn’t fix your problem, then you may be below the minimum requirements, but this is a good first step either way, and it’s always good to have your operating system up to date.

If you’re having problems getting the service pack to install on Windows XP or Windows Vista, check out the post below by TheHolst for a workaround.

    -The Problem with that solution is that a lot of people get the “Access Denied” when trying to install service pack 3. I too have this problem.
    I have tried every solution to be found in Microsofts own guide (http://support.microsoft.com/kb/949377)
    I’ve tried Fix It (no luck)
    I’ve tried google and been to one forum after the other (No solution yet)
    It seems to me that there are no more options left…
    I’ll write here IF I find a solution… But morale is low :-(

        I haven’t found any reason for this problem yet. Guess i need to reinstall… Hmm now where did I put my windows disc….

        Found a solution… I think.
        It’s installing now atleast. I found this guide for Windows Vista and tried it in Windows Xp. Looks like it’s working :-D
        Guide Here:

        1. In Windows XP, click Start and click Run, then type regedit and hit enter. In Windows Vista, click Start and type regedit in the search box and hit enter.
        2. Go to HKEY_LOCAL_MACHINE\System\Currentcontrolset\Control\Windows
        3. Look for the key named CSDVERISON and right click it, then hit modify (DO NOT click “modify binary data” on accident). You should see 100 if you’re currently on SP1, or 200 if you’re on SP2. If you’re using Windows XP, change it to 300. If you’re using Windows Vista, change it to 200.
        4. Restart your computer and try the D3 install again.

        Basically this tricks the installer into thinking that the latest service pack is installed.

        (Edited by TheDizle) I only recommend this for users who aren’t able to install the latest service packs and can’t find a good solution. I would also not use this as a permanent solution, I would keep trying to find a fix to be able to install the service pack, or eventually reinstall your machine if you can’t find a good fix.
