I suppose you generated that log after winetricks wsh56, right ? still, looks like some lines are missing from the log :( could you do this as well: WINEDEBUG=+module,+file wine regsvr32.exe scrrun.dll &>/tmp/log.txt and after compressing /tmp/log.txt (with bzip2) put the file /tmp/log.txt.bz2 somewhere up on a server where i can get it to have a look?
