I deleted my .wine, next I run winecfg in order to create .wine directory and then I just copy paste the program files directory from my old ubuntu .wine directory into the new fedora .wine directory. The error message wine: cannot find L"C:\\windows\\system32\\wineboot.exe" deasapear. But warcraft 3 still not work. Without opengl it is too slow (very slow, unplayable) and there is a lot of line such as : err:d3d:loadVertexData >>>>>>>>>>>>>>>>> GL_INVALID_ENUM (0x500) from glVertexPointer(...) @ state.c / 4346 with -opengl option the speed seems to be good but all button are transparent. Thus I will reinstall it. What is the best procedure about wine when you change your computer ? Do you must install all program you had on your old computer ? Thanks for your help
