https://bugs.winehq.org/show_bug.cgi?id=56940 --- Comment #7 from Louis Lenders <xerox.xerox2000x(a)gmail.com> --- Created attachment 76768 --> https://bugs.winehq.org/attachment.cgi?id=76768 test executable Attached a small test executable On windows this will start regedit, on wine it does nothing... After long search, if I'm correct, the problem is in ShellExecuteW. Source for simple test: #include <windows.h> #include <shellapi.h> int __cdecl main(int argc, CHAR *arg[]) { ShellExecuteW( NULL, L"open", L"regedit.exe ", NULL, NULL, SW_SHOWNORMAL ); } Wine's ShellExecuteW doesn't like the trailing space, but windows seems to happily execute the app. I'll see if I can fixup a patch -- Do not reply to this email, post in Bugzilla using the above URL to reply.
