That doesn't make any sense to me on a call to LoadLibrary(). I haven't called GetProcaddress() yet. The DLL (and the application) are both compiled with VS++ 2005 SP1. What could be going wrong? visual-c++ loadlibrary share|improve this question edited Jun 27 '09 at 17:28 asked Jun 27

Should it fail ::LoadLibrary? –Janusz Lenar Mar 17 '10 at 17:21 If DllMain sets 'last error' as 127 and then returns FALSE, will 'last error' be overwritten by the system before returning from ::LoadLibrary? –Janusz Lenar Mar 17 '10 at 17:25 add a comment| 8 Answers 8 active oldest votes up vote 16 down vote Let's take this step by step: The error message means that the dll was found but a required function is missing. (Jitter is right.) This implies that you have the dll you need, but not the right version. (Davefiddes is right, although the problem can be any dll, not just the Microsoft runtime library. And, at least for major updates, Microsoft gives its runtime libraries different names, so in that case it wouldn't be an issue.) This doesn't make sense, because no function has been requested from the dll being loaded. (Adam is right.) Therefore, the missing function was expected to be found not in the dll which is being explicitly loaded by the LoadLibrary command, but in a dependent dll which is being implicitly loaded at the same time, because the first dll requires it. (Zebrabox was close.) A dependent dll is a dll that is "statically" linked to the library being explicitly loaded, via an im

It's sounds very easily, but I didn't finf any information about it. I've a C# solution with excel Add-in and winforms application and library project with only one method. project with library have next code: [DllImport("Kernel32.dll", SetLastError = true, CharSet = CharSet.Ansi)] public static extern IntPtr LoadLibrary(string filename); public sealed class LibraryInfo { public readonly IntPtr Handle; public LibraryInfo(string dllName) { Handle = LoadLibrary(dllName); } } public LibraryInfo http://stackoverflow.com/questions/33390797/loadlibrary-fails-with-error-code-127 GetLib(string name) { return new LibraryInfo(name); } Look's like simple. So I've a call of that method from add-ins and from WinForms I've a Dll, builded for x64 platform and x86 platform. And now magic: LoadLibrary returns error code 127 only when I run it from Add-in and x64 configuration and on excel-2016(x64, ofcourse). When I run it on x86, or winform (both x86 and x64) it works. And it is not all, when I run it on Excel 2013 it's works fine too!!! mayby somebody knows? c# excel winapi 64bit loadlibrary share|improve this question edited Oct 28 '15 at 14:43 IInspectable 16.1k21957 asked Oct 28 '15 at 12:14 qpIlIpp 93 Would it be possible to format your code as code. The edit window has help for how to do that. That way you can get decent syntax highlighting and indentation. As it stands, the code here is hard to read. –David Heffernan Oct 28 '15 at 12:23 add a comment| 2 Answers 2 active oldest votes up vote 0 down vote Error code 127 is ERROR_PROC_NOT_FOUND. The specified procedure could not be found. Typically that means that something is calling GetProcAddress which is failing because the module in question does not export a function of the speci
