Ensure that you're using the latest version of Indy 9. You can download the latest version from the Indy website.
If you have followed all steps and still get the error, you need to debug the DLL loading process.
This works if your application only needs to connect to servers supporting older protocols (TLS 1.0 or SSL 3.0 – insecure, but sometimes unavoidable in legacy intranets). Delphi 7 Indy 9 Could Not Load Ssl Library
Steps:
Why this may fail:
Even with the correct DLLs, modern servers (e.g., Gmail, Stripe, AWS) have disabled TLS 1.0 and 1.1. The handshake will fail with a different error, or the connection will be rejected silently. You might see “SSL negotiation failed” after loading the libraries. Ensure that you're using the latest version of Indy 9

The "Could Not Load SSL Library" error usually indicates that the Indy library is unable to find or load the required SSL/TLS library (e.g., OpenSSL). Indy 9 relies on external libraries for SSL/TLS support, which are not included with Delphi 7 by default. Why this may fail: Even with the correct
Before we get to the solution, let’s acknowledge the common traps:
Ensure that OpenSSL libraries are installed on your system. You can download the OpenSSL libraries from the official OpenSSL website. Make sure to download the correct version (32-bit or 64-bit) that matches your Delphi 7 installation.
