err:module:import_dll Loading library MSVCP140.dll
I'm having trouble loading the msvcp140.dll. The problem started when I migrated a project from 32-bit to 64-bit. I've swapped out my dlls from 32 to 64-bit so I'm not sure what the problem is.

Some reading material, if you don't know already:

https://wiki.winehq.org/FAQ#Wineprefixes
If your winetricks is up to date and you made a 64-bit wineprefix (you probably did unless you set WINEARCH when making it, and everything actually is 64-bit, etc.) then 'winetricks vcrun2015' will (try to) install both 32- and 64-bit versions.
(Further info: just moving around DLLs may not be enough, overrides may need to be set in winecfg but in general using winetricks will do that automatically.)
