@cyberdragon442(View Post) For the first issue, try adding a slash or backslash after the folder name, so C:\Derp\Herp becomes C:\Derp\Herp\ If you made any changes to the source, especially commenting out important header files, that will not work because you're missing out parts of the source. I could send you my project folder, but it's large in size. Try this: Download the Powder Toy solution from the wiki's compiling for windows area, then download the zip of the latest source from http://github.com/facialturd/The-Powder-Toy/ and then extracting into the solution folder. After that. open Visual Studio and the project and drag "embr.c" into the "Elements" folder list.
