What does not
App cannot open the downloaded epubs (from acsm files), it claims they are corrupt.
The described workaround with the wine32 prefix and winetricks worked.
What was not tested
Syncing books in the cloud.
The app will want to update immediately, which won't work. The installer for 4.5.7 will crash.
