Solving error MSB8011: Failed to register output

This error happens when Visual Studio (2010) can't find the dependent dll files that are required by the program for creating the OCX. The OCX is created in the Debug directory of the project (for Debug builds), and specifying the "Working directory" (in project settings) as the folder where the dependent DLL's are, won't help Visual Studio in locating the DLL's.

Now the catch is (this is what makes it a headache to solve the problem) that sometimes, without Visual Studio being able to create the OCX, you won't be able to run Dependency Walker on the OCX. So you'll never figure out that the missing DLL's are the problem.

If you know which DLL's need to be placed in the Debug folder, just place them there, and the error will disappear. If you don't know, and if your OCX didn't get created, then go to project settings > Linker > General > Register Output and set the value to "No". This will create your OCX for you, but won't go through the process of registering it, which is when it needs the dependent DLL's.

Once you double-click the OCX and Dependency Walker shows you the missing DLL's with yellow circle icons, just place those DLL's in the same folder as the OCX, and your program will work fine. It's that simple.

The issue could be that your project tries to register a COM object, but there are not enough privileges to do that. On Windows 7 and 8 regsvr32 requires administrative permissions.

What you can do is the following. Create a shortcut on your desktop to C:\Windows\SysWOW64\cmd.exe (the 32-bit console). Right click, Properties -> Advanced -> check Run as administrator. Launch the shortcut, and make sure User Access Control pops up, and click Yes. Start building from this special console window.

I tried using run as "Administrator" VS 2015, it's able to solved the problem
