Delphi 7 Indy 9 Could Not Load Ssl Library Jun 2026

His heart went cold. "No," he whispered. "No, no, no."

Some OpenSSL distributions require the Microsoft Visual C++ Redistributable to be installed on the machine. Without it, the DLLs will fail to initialize. Delphi 7 Indy 9 Could Not Load Ssl Library

To resolve the error, you need to download and install the correct OpenSSL library version compatible with Indy 9. His heart went cold

Indy 9 was compiled against OpenSSL or early 1.0.0 headers. The function signatures and memory management have changed drastically since then. Indy expects specific export names and specific SSL_METHOD struct layouts. If you feed it a newer DLL, the LoadLibrary call might succeed, but SSL_CTX_new will fail silently, and Indy gives up. Without it, the DLLs will fail to initialize

But here is the "Gotcha": Delphi 7's IdSSLOpenSSLHeaders unit initializes the library using LoadLibrary . If the DLLs are not in the (which is not always the EXE directory if you use shortcuts or open files from other locations), it will fail.
