Hi guys! Very excited that 1.4 came out for Prepar3d.. I'm a bit bummed that I already purchased the FSX one only a week ago though :/ My question is, when I go to install the product, I enter order code.. then in next screen, it doesn't automatically find the simulator folder, regardless wether I'm using the migrator tool or not. The 'NEXT' button is greyed out, no matter which folder I select. I scoured the forums and googled.. but could not find any answer. Guys I'd love some help desperately if you could. I essentially have purchased this product twice and have no way of running it. Your help will be most greatly appreciated! Kind Regards, J

It sounds like the activation isn't working. Try a Manual Offline Activation.
