I installed DPP 4.16.10, but it crashes every time it opens. It opens briefly, I see the window, and a few seconds later it closes. Same with DPP 4.15.20 which I also tried as 16.10 crashes. Running Windows 10 64-bit, version 10.0.19044 Build 19044.

Windows Event Viewer lists a crash of .NET, followed by a crash of DPP, followed by an information post with some more details contained in a Windows error reporting file.

I don't have that folder that some people say to delete. I've tried running in compatibility modes for Windows 8 and Windows XP SP3 with no success. Anything else I can try?
