Again: just doing 'sudo yum install libpng' won't fix it.
To install the 32-bit lib: 'sudo yum install libpng.i686'
For further problems please seek help in WineHQ user forums, Bugzilla is not meant for end user support (this is obviously the case here).
Regards
I already had 32-bit libpng's installed before my first post in this bug report. I decided though to uninstall Wine, restart, then reinstall Wine. I then installed .NET 4 under 32-bit Windows XP prefix. Tried launching ROTT and same exact output as before.
