I installed both 32bit and 64bit version of OpenSSL libs on Vista x64. The 32bit version was installed in
c:\Program Files (x86)\OpenSSL and the 64bit version was installed in
c:\Program Files\OpenSSL. Then I added the entry
%ProgramFiles%\OpenSSL to the
PATH environment variable.
%ProgramFiles%\OpenSSL is expanded to
c:\Program Files (x86)\OpenSSL for 32bit programs and it's expanded to
c:\Program Files\OpenSSL for 64bit programs. The idea is to have 32bit programs use 32bit version of OpenSSL libs and 64bit programs use 64bit version. I wanted to check if this works by running 32bit cmd.exe and issuing
where ssleay32.dll and then by running 64bit cmd.exe and issuing the same. However in both cases I get the error
INFO: Could not find files for the given pattern(s).
This is a follow up to Different PATH environment variable for 32bit and 64bit Windows - is it possible?
