Using the latest version of U++ ( 8227 ) and choosing the menu Setup | Automatic setup... I enter the path to the SDK version 7.1a on my machine for VC++ 12.0. I then click the OK button. But when I next open the same dialog the path I entered is gone.
I cannot use VC++ 12.0 if the SDK paths are not there when I try to build.
That is OK. This is dialog for automatic setup of build methods. After hitting OK, build methods are created and are later editable using Setup/Build methods.
