SQL 2012 install on Server 2012R2 “Error while enabling Windows feature NetFx3”

Problem… “Error while enabling Windows feature NetFx3″

We wanted to install APP-V 5.x on server 2008 running SQL 2008. At the very start this was a problem. Error you require a later version of the OS etc.

So we deployed 2012 R2, and then started to install SQL 2012….. error during install …

“Microsoft SQL Server 2012 Release Candidate 0 Setup
The following error has occurred:
Error while enabling Windows feature: NetFx3, Error Code: -2146498298, Please try enabling
Windows feature: NetFx3 from Windows management tools and then run setup again.”

Cancel install

We then tried to enable .NET Framework 3.5 on Windows Server 8 using the “Add Roles and Features Wizard” of Windows Serve 2012.

“Failed”

Next attempt.

Load 2012 disk & connect the server to the internet

Launch CMD as administrator

dism /online /enable-feature /all /featurename:NetFx3 /source:d:\sources\sxs

The operation finished successfully from the command prompt.

We then were able to install SQL Server 2012 successfully.
