SQL Server 2012 setup failed during installation because of this error with error code "0x85940001" and message
"Error while enabling Windows feature : NetFx3, Error Code : -2146498298 , Please try enabling Windows feature : NetFx3 from Windows management tools and then run setup again. For more information on how to enable Windows features , see http://go.microsoft.com/fwlink/?linkid=227143"
We know this due to one of the feature in windows 2012R2 (NetFx3) was note enabled during the setup time. We were unable to cancel the setup and proceeded until end with following services "Database engine, Reporting services, Analysis services, Client tools, SQL Server Data Tools, Data Quality Services, SQL Server Replication, Master Data Services" failed during setup.
If its a standalone server I have uninstalled all components restart server and reinstalled from first,
