Delphi 7 Indy 9 Could Not Load Ssl Library

Then call:

Do not try to "modernize" by dropping in OpenSSL 3.0. Do not expect Windows to provide it. Instead, treat these two DLLs ( libeay32 and ssleay32 ) as permanent artifacts of your application, ship them in your install folder, and they will continue to work for another decade.

uses IdSSLOpenSSLHeaders; procedure ForceSSLLoad; var ExePath: string; begin // Get the directory where the EXE lives ExePath := ExtractFilePath(ParamStr(0)); Delphi 7 Indy 9 Could Not Load Ssl Library

Add this to your main form's OnCreate or in a initialization section:

// Attempt to load if not LoadOpenSSLLibrary then raise Exception.Create('Failed to load SSL library from ' + ExePath); end; Indy 9 (specifically the version included with D7) does not have the modern IdSSLIOHandlerSocketOpenSSL methods. You need to use the global variable. Then call: Do not try to "modernize" by

OpenSSL 1.0.2u (built for VC6).

IdSSLOpenSSLHeaders.IdOpenSSLSetLibPath('C:\YourExePath\'); Call this BEFORE you create any TIdSSLIOHandlerSocket . If you call it after, Indy has already cached a "not found" result. This is the most overlooked issue. OpenSSL 1.0.2u (for Win32) was compiled against Microsoft Visual C++ 2008 or 2013 . Delphi 7 applications use Borland's own runtime (not VC runtime).
