.net Framework on Server 2012

Im trying to install Quickbooks 2010 on a Server 2012 for an accountant. I keep getting this error "The following feature couldn’t be installed:
.NET Framework 3.5 (includes .NET 2.0 and 3.0)

Windows Server roles and features cannot be automatically installed or uninstalled via the Windows Features Control Panel."

I goto Roles and Features and its already installed.

Hello ThereSystem AdministratorCommented:
1. Programs and Features -> Turn Features On/Off -> enable .NET 3.5 and lower

2. Using dism.exe should solve your problem if you have the ISO: dism.exe /online /enable-feature /featurename:NetFX3 /Source:D:\sources\sxs /LimitAcces
without ISO: dism.exe /online /enable-feature /featurename:NetFX3 /all

3. Missing updates might cause this. HERE
This behavior can also be caused by a system administrator who configures the computer to use Windows Server Update Services (WSUS) instead of the Microsoft Windows Update server for servicing. HERE

4. Or just type an alternate path that will point to X:\sources/sxs folder. HERE
