According to google this error means installer tries to load x64 dll instead of x86 dll, which means there is probably a rogue visual c++ dll somewhere on your system, probably installed by some other program incorrectly. You can try to use dependency walker [url]http://www.dependencywalker.com/[/url] and see which msvc dll it tries to load and get the path to that dll. Or, if you fele like this is too complicate to debug, add me on skype (cenarius21) or find me on discord and we can take a look tomorrow.
