As is said on this Question (Can't run Office 2013 using Wine 2.0) to solve the black screen issue in Office 2013 using wine, one needs to edit the HKCU\Software\Wine\Direct3D\MaxVersionGL value. I have searched wuth regedit and in the playonlinux reg.editor but i cannot find the Direct3D folder/files. Am i missing something?
