Now just build your DLLand run Tacview to see it in action! (You'll have to close Tacview, build your add-on, then re-launch Tacview each time)


In the case that this error message appears in the log:

Make sure the latest version of Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 has been installed on this system:""

Make sure that you are not attempting to run a DEBUG version of this addon if you are not a developer. DEBUG builds require additional DLLs and tools.

First, use the link provided to download the latest version of Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019, even if you are sure that you have already downloaded everything your need. Close and re-launch Tacview.

If the error is still occurring it could be caused by the DLL having been compiled in DEBUG mode and now being run on a computer that is not set up for debugging. If you are the developer, be sure you are compiling the DLL in RELEASE mode. If you are not the developer, please contact the developer.
