# 4: Open the generated 'builddir_vslite_vs\zstd.sln' and build through a project, which should explicitly add the above to
# the project's 'Executable Directories' paths and build successfully.
# 5: Remove 'C:\Windows\system32;C:\Windows;' from the same project's 'Executable Directories' paths and rebuild.
# This should now fail.
