Wine DLL error

If you get an error like that:

wine Program.exe
err:module:attach_process_dlls „SomeRelatedDLLinSameFolder.dll“ failed to initialize, aborting
err:module:LdrInitializeThunk Main exe initialization for L“path/to/Program.exe“ failed, status c0000005

And you have tripplechecked, that the application is supported properly by wine, it might even have worked before, the DLL file is not damaged and you do not know what to do now?

Check if the volume where Program.exe and especially the dll file are on is mounted with an exec flag or whether the files have the exec flag. Otherwise wine just won’t start the dlls!

Update: There’s a feature request going on in order to implement a descriptive error when wine notices that it can not execute a dll file. See WineHQ Bugzilla #11661.
