You check your code. It hasn’t changed in a decade. Your heart sinks. You search forums, only to find dead links to “OpenSSL 0.9.8” from 2005. You try copying ssleay32.dll and libeay32.dll from random websites, only to get access violations or the same error.

Your Delphi code changes to TIdHTTP.Get('http://localhost:8080/api/data') . No SSL libraries. No Indy 9 headaches. You win. Delphi 7 Indy 9 Could Not Load Ssl Library
Honestly? The easiest path is to set SSLOptions.Method := sslvSSLv23 and then explicitly disable SSLv2 and SSLv3, which leaves TLS 1.0, 1.1, and 1.2 enabled. You check your code
