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?

Roseanne from the winehq just replied and give the missing idea: If it doesn't exist....create it! Here you will find the answer: https://appdb.winehq.org/objectManager.php?sClass=version&iId=26323 Just add the new key with the value in regedit or in the regedit of playonlinux.
