I got the latest source code from the OpenStudio gethub site. I followed the Super Build directions for Windows and VisualStudio 2013 Win64. When I run CMake it tries to download OpenSSL 1.0.2.a (64-bit). After a while I get the following error:

Downloading OpenSSL 1.0.2a (64-bit) [download 0% complete] CMake Error at CMakeLists.txt:135 (file): file DOWNLOAD HASH mismatch

for file: [C:/GitHubClones/OpenStudio/Build/]
  expected hash: [3f9c88523634c7b1e27f4026e7c3f3ee]
    actual hash: [904a301f256f6ca9910d81671efcdd27]
         status: [28;"Timeout was reached"]

Does anyone have an idea as to what I'm doing wrong?

I would suspect a firewall or some network problem, can you see if is being created in your build directory?

Folder '...\' is invalid". If it is a firewall issue, is there someplace I can get the zip file and if I manually place it in the build folder, will that work?

Can you try deleting the file and configuring again to re-download it? If that doesn't work the url is
