There are 2 versions of SketchBook that can run on PCs.
DESKTOP
WIndows 10 (Tablet)

To enable pen mode, {=] > Preferences
NOTE: With Subscription, you can run the DESKTOP and WINDOWS 10 version of SketchBook. The DESKTOP version has more features and works best with Wacom tablets (Intuos Pro/Cintiq). The Windows 10 version is designed for Tablets and has Pen Mode (Surface). It has slightly less features but we are working on it so that there will be parity to the desktop version.
