Hello. I am running wine-staging-2.20 with win32 WINEARCH.
After I followed the installation instructions from here
(https://appdb.winehq.org/objectManager.php?sClass=version&iId=32129), my
GOGGalaxyClient launches with some error boxes of wine and is grey-blank.

Can someone help me to fix that?
Here is also my wine log (https://bpaste.net/show/75aac5cb3890)
