HKCU\Software\Binary Fortress Software\DisplayFusion

If there isn't, could you try creating it, and pasting your Steam license key into it? ]]> https://www.displayfusion.com/Discussions/View/df-not-starting-just-purchased-on-steam/?ID=f96cc24c-b8e7-4f64-a7f4-8e58d221c7e4#4 Wed, 17 Jun 2015 18:08:57 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-not-starting-just-purchased-on-steam/?ID=f96cc24c-b8e7-4f64-a7f4-8e58d221c7e4#4 DisplayFusion I receive the Steam error every time at startup still, so I guess this hasn't been fully resolved.. ]]> https://www.displayfusion.com/Discussions/View/df-not-starting-just-purchased-on-steam/?ID=f96cc24c-b8e7-4f64-a7f4-8e58d221c7e4#3 Tue, 16 Jun 2015 23:16:43 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-not-starting-just-purchased-on-steam/?ID=f96cc24c-b8e7-4f64-a7f4-8e58d221c7e4#3 DisplayFusion This worked, however it still said something about the steam key, but all looks ok in the settings. ]]> https://www.displayfusion.com/Discussions/View/df-not-starting-just-purchased-on-steam/?ID=f96cc24c-b8e7-4f64-a7f4-8e58d221c7e4#2 Tue, 16 Jun 2015 19:08:29 GMT Binary Fortress Software https://www.displayfusion.com/Discussions/View/df-not-starting-just-purchased-on-steam/?ID=f96cc24c-b8e7-4f64-a7f4-8e58d221c7e4#2 DisplayFusion Responded in the Steam discussion topic, please let me know if you still run into any trouble after trying my steps there
