I am trying the same as the post above and the actual error is:
the ordinal 284 could not be located in the dynamic link library
SSLEAY32.dll
I searched for that dll and it is not to be found. windows forums provide
vague directions to reinstall Windows, which I cannot do because this is a
company PC and IT will be happy to tell me that's why open source programs
are not supported and not encouraged.
any suggestions are appreciated.
