As far as I understand, in order to make a DLL COM we error loading type library dll visual studio 2015 need to define its interface in a .idl file, compile it with the MIDL compiler and then simply implement the classes that use the defined interfaces. Then we need to expose error 80029c4a the DllRegisterServer, DllUnregisterServer and DllGetClassObject. and it should be enough, right?

When I run the application, it gives the following error: Unable to cast error loading type COM object of type 'System.__ComObject' to interface type 'Microsoft.Office.Interop.Excel.Application'. This operation failed because the QueryInterface call on the COM component for the interface with IID '{000208D5-0000-0000-C000-000000000046}' failed due to the following error: Error loading type library/DLL. (Exception from HRESULT: 0x80029C4A (TYPE_E_CANTLOADLIBRARY)). It was working fine before I've upgraded Visual Studio from 2010 to 2012. I've also upgraded Office from 2010 to 2013.

Aug 24, 2014 01:39 PM|martinhansenlennox|LINK I'm having problems with a fresh install of VS Express 2013, I'd really appreciate some help or even pointers as to how I can debug these types of issues. I have ensured the system path is under 2000 chars (it's 600). I haveun/reinstalled numerous times. It always seems to go ok, but when I open the application I am having 3 problems - I'm not sure if they're related or not: One When I try to create a new Project, it just gives me the following alert box: Error loading type library/dll. Exception from hresult: 0x80029c4A TYPE_E_CANTLOADLIBRARY And when attempting a new Web Site, it gives me: Exception has been thrown by the target of an invocation. Two After installation I'm missing an exe file in the start menu. The folder for VS 2013 is there, but it just says "empty". Sure I can find the exe file and pin it to the start menu / taskbar, but I'm thinking this is an indication that something has gone wrong? Three Thirdly, when I open an existing project (created in VWD 2010) and perform a build, the build fails, but it gives me no messages in the Errors window. Thank you in advance for any help, suggestions or advice you can offer. reinstall VS2013 Reply ignatand
