Just open the file ~/.wine/user.reg then look for a line like comctl32=native,builtin or the like , and remove it. winecfg has a "per application" setting for native dlls ( apart from default). See the wine user manual. However , i prefer to set it from the command line; if you want run with native comclt32 for example just do: WINEDLLOVERRIDES="comctl32=n" wine dameware.exe
