I'm having this EXACT same problem. The only difference is my 3dxchange version is 7.61. Also the links on this page no longer work.
I should add that I ran your reg edit for DX11 & DX9, and the problem occurred with both settings - 3DX Pro failed to launch. Thank you for your help, Don
Hi Doxa, Thank you for your feedback.Did you install Duet?If Yes,please uninstall Duet and launch 3DXchange agin. Molly Reallusion
I'm having the same issue with 3DX 7.4 Pro. When I start it, the splash screen appears for a few seconds and then a white (blank) window opens for about one second and then closes. I've uninstalled 3DX and reinstalled, but it did the same thing. My machine is an HP laptop with an I7-8750H, 32GB RAM, 4TB SSD, and two 4K monitors. The video card is an NVidea RTX 2070. I've attached the 3DX splash screen and I was able to catch the 3DX window just as it was closing. Please let me know if you need additional information. Thanks, Don
Hi rhashad, Can you try 3DX dx11? Molly Reallusion
I have the same issue as stated above When I try to run the DX11 version, following the "Read Me" I get an error saying "Load msx Error"

Hi, billing_49, I have got it.Thank you very much. Molly Reallusion
Hi! I found this thread: https://www.reallusion.com/FeedBackTracker/Issue/3dxchange-crashes_2 When I uninstalled "Duet" 3DXchange is now working. This seems like something that should be documented somewhere.
Hi, billing_49, Can iClone7 open?If Yes,please provide 3DX log file to us.Attach the file in your next comment. Download the zip file with the link below, inside the zip you can find the description about how to generate the startup log and crash dump. https://goo.gl/YgVYhF Molly Reallusion
As I said in my previous comment; still doesn't open, even with ignoring the load msx error.
Thanks for your help. Molly Reallusion
Hi, It still doesn't work; it's the same issue where it opens a window (just white), then immediatly shuts down.
Hi, billing_49, As described in the previous comment, please ignore the "Load msx Error" message, and let us know does 3DXchange completed the launch process and ready to use? Donnie Reallusion
