I get asked this quite often. So I have decided to blog this again.
You can download the Autodesk Inventor 2015/2016 tutorial files from this location:-
If you go to link above, and then scroll right down to the bottom, you will see these files to download.
Unzip the files to your C:\Users\Public\Documents\Autodesk\Inventor 2015\Interactive Tutorial\ folder.
In Inventor just activate the Tutorial Project and you are then ready to go with the dataset for the Tutorials.
In Inventor select OPEN and browse for any of the needed.
To actually run through the Tutorials, this can be done in Inventor by going to TOOLS > LEARN MORE > TUTORIALS accessing the online link
Or use the following link in you Internet Browser
This should solve the problem.
