When launching the Xpress tools (SimulationXpress, FloXpress, DFMXpress, DriveWorksXpress) in SolidWorks 2015, it kept prompting for a product code. I am asking to check if I am the only one experiencing this. I discovered this when I wanted to use them, but did not have an internet connection. It was pretty annoying!

I finally managed to resolve it by visiting MySolidWorks.com, and registering each product individually with my serial number, and keying in their respective product code. I hope that it stays permanently!
