Delphi 7 Indy 9 Could Not Load Ssl Library -

If you cannot modify or recompile your legacy Delphi 7 code, you can route your network traffic through a local proxy running on the host machine.

Delphi 7 links to MSVCRT.DLL (the system C runtime). Old OpenSSL 0.9.8 (for VC6) also links to MSVCRT.DLL . That works perfectly. Newer OpenSSL 1.1+ links to MSVCR90.dll or VCRUNTIME140.dll . Indy 9 cannot load these because the function names are decorated differently. Delphi 7 Indy 9 Could Not Load Ssl Library

While the steps above will make the error disappear, they introduce significant security risks. OpenSSL 0.9.8 has been obsolete for many years. Modern websites and APIs often require and strong cipher suites. If you cannot modify or recompile your legacy

The files libeay32.dll and ssleay32.dll are not in the application's executable directory or the system path ( C:\Windows\System32 ). That works perfectly

A: Your development machine likely has the OpenSSL DLLs in a system path (e.g., C:\Windows\System32 ), or the DLLs are present in your project's output folder. The client's machine does not have them. The fix is to include the DLLs with your application distribution as described in Step 5.
