Your step (4) to me appears to be wrong. If you are to install openssl to the following directory: C:\Program Files (x86)\OpenSSL\ then you need to do: ? perl Configure VC-WIN32 -prefix=C:\Program Files (x86)\OpenSSL When I build openSSL I use nasm, so after the above I do: ? ms\do_nasm ? nmake -a -f ms\nt.mak ? nmake -f ms\nt.mak test ? nmake -f ms\nt.mak install Does that help at all?
