Hi Martin Thanks a lot. That was exactly my scenario. Even deleting the *.obj files was not helping . Deleting the folder and cloning again worked .

Hello Madhusudan, Just an idea: Have you built the x86 version before in the same directory tree? Quite some time ago, with a very much older version of openSSL, I ran into a similar problem when I tried to build on Windows. Since that time, I always build the x86 and x64 versions in different directories.
