http://bugs.winehq.org/show_bug.cgi?id=59201 mmgenc10@gmail.com changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |mmgenc10@gmail.com --- Comment #3 from mmgenc10@gmail.com --- I've also been working on getting this application to work under Wine WoW64. I've done some debugging and I think I've narrowed down the issue: Page fault seems to occur because kernelbase.dll LocalLock function returns NULL and mfc80u.dll doesn't check the returned pointer before using it. LocalLock checks the validity of the memory section by executing a dummy write. However the memory section it is called with points to .rsrc section which is read-only. So, LocalLock rejects it and returns NULL to indicate failure. I've got around the issue for now by modifying toolbox.exe's resource section to be read-write. This allows the application to launch. However there seems to be some other issues as well because it displays cryptic error messages at random intervals. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
