less than 1 minute read

Description:

Follow these steps if you keep getting errors when attempting to install .NET 3.5 or 2.0 on Windows Servers.

To Resolve:

  1. Search – cmd – Run As Administrator – Type:

    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All
    
  2. If it still fails, load your installer disc and type:

    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:d:\sources\sxs
    
  3. Alternatively, you can use Powershell:

    Install-WindowsFeature Net-Framework-Core -source \\network\share\sxs
    
    #or D:\sources\sxs. Run get-windowsfeature afterwards to make sure it installed.
