Well that sounds very plausible, but I am puzzled as to where I should alter this. I have installed the Boost library in the usual way and chosen the solution by opening it from File Open solution The Path of the solution is shown in the Properties page below \\Hetp3\i$\boost_1_33_0\libs\test\build\msvc71_proj\boost_test_library.sln but is greyed out so I can't alter it. I am building and running unit_test_example1 project. The project property page shows .\Debug/unit_test_example1.exe as the output file. It is set as the startup project and I press ctrl F5 So where/how can I alter the descriptor to use a single backslash? (Or just remove the computer name from the path?)

The fix is to use a single backslash.
