Hmm and can you compile some VST example without this failure? Maybe you forgot compile validator? (depends of how you created your project)
Or try check if everything is on right place (if everything is under path from error list) (not only your plugin files but validator and etc…)
and maybe willpirkle have truth. I run VStudio as administrator and never had of this problem. Except when I didn’t right plugin setup project or vst is not compiled right.
