What do you mean by "AmiSSL won't run" - exactly what isn't working? Accessing sites over https with IBrowse?
AmiSSL just needs and assign for its stuff, AmiSSL:, where it keeps its libs and various cert directories. Do you have this assign?
If you do, and IBrowse still doesn't load sites of https, it could be worthwhile testing with the openssl binary and see what it says...
amissl:openssl s_client -connect forum.amiga.org:443 -CApath AmiSSL:certs
