--- Comment #5 from Louis Lenders xerox_xerox2000@yahoo.co.uk 2008-08-19 08:55:18 --- hmm, it looks like it even crashes earlier. Another thing you might try is remove riched20 again as a native library ( start winecfg, and look under the Libraries tab, and remove it). Then try run with native oleaut32:
'wget http://kegel.com/wine/winetricks && sh winetricks vcrun6'
Then run the app with:
WINEDLLOVERRIDES="oleaut32" wine app_name.exe
If that doesn't help either i guess you have to generate some debugtraces
