When debugging an application with boost::posix_time::ptime instances in it, the normal debugger is not very helpful, as it only shows a time value in ticks. When outputting the same object with std::cout, the console shows the time in a readable format.
Now I know of the existance of debug visualizers, which can format the values to a readable format in the debugger. There is even a handy installer for a tool that includes the debug visualizer for boost::posix_time at msdn.
However, when trying to install this tool, I get the error message "This extention is not installable on any currently installed products.". Maybe this is because I am using an express version of Visual Studio 2012, but I don't think so, as it does support other tools and extentions.
Boost does provide the files to install the debug visualizer, but there is no help regarding how to install them. Visual Studio help only mentions how to install some .DLL files with the visualizer in it, while the files provided by Boost are .txt and .hpp files.
So, I still don't know how to install a visualizer for boost::posix_time. How do I do this?
I'm not sure if the Express versions even support installing debug visualizers as their extensibility is fairly restricted.
VS2012 also uses a new format for the debug visualizers so unless the ones you are trying to install are in the new format (which is XML-based IIRC and not backward compatible) you're not going to get anywhere with them. The ones you linked are in the old format, and to install them on a pre-VS2012 Visual Studio, you put them into the appropriate sections of the autoexp.dat file that you find in the Visual Studio directory tree.
