// Manually load the libraries from the EXE path SetDllDirectory(PChar(ExePath));
Here is a minimal, safe configuration for Indy 9 when using OpenSSL 0.9.8 (legacy servers):
The error in Delphi 7 using Indy 9 occurs because Indy cannot locate or successfully initialize the external OpenSSL dynamic link libraries (DLLs) required for encrypted communication.
If you need further assistance, the Indy project's documentation and community forums are excellent resources. For issues related to TLS protocol versions after the DLLs load successfully, you may need to adjust the SSLOptions.Method property of the SSL IOHandler to enable TLS 1.2.

If you've followed all the steps but your application still fails, the problem might be with the operating system environment.
Next, the ones from a old SVN repository. Error.
If you are trying to upgrade your components or implement a specific workaround, let me know: // Manually load the libraries from the EXE
The error in Delphi 7 with Indy 9 is typically caused by missing or incompatible OpenSSL binaries . Because Indy 9 is extremely old, it relies on specific, often customized, legacy builds of OpenSSL that differ from modern standards. 1. Primary Cause: Incompatible DLL Versions
If you're developing a Delphi 7 application that utilizes Indy 9 for networking, you might have encountered the frustrating "Could Not Load SSL Library" error. This issue typically arises when your application attempts to use SSL/TLS encryption, but the required libraries are not properly loaded. In this blog post, we'll explore the possible causes and provide step-by-step solutions to resolve this common issue.
// Pre-load the libraries to catch errors early if not LoadOpenSSLLibrary then raise Exception.Create('Failed to load SSL libraries from ' + Path); end; If you've followed all the steps but your

If you need TLS 1.2 or 1.3 support, note that OpenSSL 1.0.2 supports TLS 1.2 but TLS 1.3. For TLS 1.3, you genuinely have no choice but to migrate to a modern Delphi version (10.x+ with Indy 10). But if your legacy app needs to connect to an old server (TLS 1.0/1.1), the solution above will keep the lights on for years to come.
Note: Some custom builds are statically linked to MSVCRT – easier to drop DLLs and go.
