Could not load SSL library

[mail@hvdboogaard.nl]

Hello,
I use registerd Intraweb 14.2.8 Ultimate and Indy 10.6.2.5366 Delphi 10.2.3
And openssl-1.0.2o-i386-win32.zip from Fulgan
I have put the dll’s in the same map as the program dll (and in windows/system32, and windows/SysWow64 for trying)
The prog is 32 bit
Snippet from program:

Code:

try
    try
      Strm := TStringStream.Create;
      IdHTTP1 := TIdHTTP.Create(nil);
      LHandler := TIdSSLIOHandlerSocketOpenSSL.Create(nil);
      LHandler.SSLOptions.certfile := certfile;
      LHandler.SSLOptions.keyfile := keyfile;
      LHandler.SSLOptions.Method := sslvTLSv1_2; // sslvSSLv23;
      LHandler.SSLOptions.Mode := sslmBoth;
      LHandler.SSLOptions.VerifyMode := [];
      LHandler.SSLOptions.VerifyDepth := 0;
      IdHTTP1.IOHandler := LHandler;
      // alleen voor debug anders regel hieronder: Strm.LoadFromFile(UserSession.Exportfilenaam);
      UserSession.XMLDoc1.SaveToStream(Strm);
      IdHTTP1.Request.ContentType := 'text/xml';
      IWMemo1.Lines.Add(IdHTTP1.Post(UserSession.nxT_Algpar.FieldByName('IDeal_Site_URL').AsString, Strm));
    finally
      Strm.Free;
      LHandler.Free;
      IdHTTP1.Free;
    end;
  except
    on E: Exception do
    begin
      IWMemo1.Lines.Add(E.ClassName);
      IWMemo1.Lines.Add(E.Message);
      // Writeln(E.ClassName, ': ', E.Message);
    end;
  end;

When I run the prog as SA all goes well.
When I run it as a ISAPI dll under Abyss or IIS I get an error:
EIdOSSLCouldNotLoadSSLLibrary
Could not load SSL library.
Who knows what is wrong?
