I was trying to get the desktop graphing working as described in the link below. I get an error that the file ../../../UserInterface/bin/Debug/QuantConnect.Views.exe does not exist. That file does indeed not exist and does not seem to be configured as a target for the build.
I changed the path to be an absolute path to the Release build of QuantConnect.Views.exe which is included in the git repo.
After that I get this error and I'm lost:
WARNING: The Carbon driver has not been ported to 64bits, and very few parts of Windows.Forms will work properly, or at all

Hi Alex; sorry due to Winforms support being so sporadic we no longer support this desktop GUI and are working on an Electron replacement instead. For now please use the website IDE or the LEAN CLI.
