Use GOG - it's fully DRM-free where Impulse requires you to activate on install (meaning you could lose access to purchased software if Impulse ever shuts down, becomes unavailable or tries to blackmail customers by imposing a regular fee to keep accounts open).
thank you for this info , I would not have known otherwise. I too own original DD and I wanted to have the newest updates with widescreen support. GOG still has the promo offer going so its totally worth it.
