You sure?
" REGEDIT4
[HKEY_CURRENT_USER\Software\Wine\Direct3D] "MaxVersionGl"=dword:00030002
"
Remove the " "-marks Copy paste that into some file. Then do wine regedit filanme. And it imports the file without any output.
Mostly just for what it's worth, note that you can also just do something like the following:
wine reg add 'HKCU\Software\Wine\Direct3D' /v MaxVersionGL /t REG_DWORD /d 0x00030002 /f
