When distributing your application to end-users, you must include the same OpenSSL 0.9.8 DLLs ( libeay32.dll and ssleay32.dll ) alongside your application's executable file. Failure to do so will result in the same error occurring on the target machine. Delphi 7 Indy 9 Could Not Load Ssl Library

For email clients using TIdSMTP , it's important to set the correct port. Modern email services (like Gmail) often use with STARTTLS or port 465 for SSL/TLS. Your SSL options for port 465 should be set similarly to the HTTP example.

To help troubleshoot further, let me know if you are attempting to connect to an or a public third-party API , and whether you are open to upgrading your Indy component package . Share public link

While placing them in C:\Windows\SysWOW64 can work globally for 32-bit apps on a 64-bit OS, local deployment avoids version conflicts with other software. 4. Configure Your Delphi 7 Code He opened Windows Explorer

The ssleay32.dll and libeay32.dll files are not in the application's executable directory or the system path.

Marcus wasn't a fossil. He was a preservationist. For ten years, he had maintained the logistics system for "Ace Trucking," a regional hauler that kept the grocery stores of three states from going empty. The system ran on a Windows 2003 server, talked to a FoxPro database, and sent dispatch emails via an ancient SMTP component. It was a digital house of cards, but it was his house of cards.

Your Delphi code changes to TIdHTTP.Get('http://localhost:8080/api/data') . No SSL libraries. No Indy 9 headaches. You win.

Indy 9 does not natively implement SSL encryption. Instead, it acts as a wrapper that calls external OpenSSL binaries. When the error triggers, it is almost always due to one of three reasons:

The WhichFailedToLoad function might return a list of missing exports. This is a strong indicator that you are using a standard (non-custom) OpenSSL DLL that doesn't contain the functions Indy 9 expects.

This error means Indy cannot find or properly initialize the required OpenSSL dynamic link libraries (DLLs) on the host system. Because Delphi 7 and Indy 9 are legacy technologies, mapping them to modern SSL/TLS standards requires precise configurations. The Root Causes of the Error

Windows looks for DLLs using a specific search order. To ensure your application finds them, place ssleay32.dll and libeay32.dll into one of the following locations:
