WINEDEBUG=+wineboot,+setupapi wineboot

When I was about to install DXVK through the install script it told me that it
could not find the d3d10.dll int the syswow64 directory. So I investigated and
found that syswow64 was in fact an empty directory. I made a clean new
wineprefix with win64 architechture and the syswow64 was still completely empty
but the system32 folder was filled with alot of dlls.

When I debugged the prefix creation with "WINEDEBUG=+wineboot,+setupapi
wineboot" I saw that it put dlls from a lib64 folder into the system32 folder
(log as attachment).
