When I don't have IDEFixPack installed, there is no problem. I will try again, thank you.

Ok, thank you for your reply.

In addition, can IDEFixPack do this? Change the 32-bit Delphi compiler default floating point format, now Extended, inefficient and not suitable for SSE instructions, can it be modified into Double? The 64-bit Delphi compiler default floating point format is Double.

Oh, how can I reproduce this problem without installing IDEFixPack? Thanks

Thanks, I have uninstall IDEFixPack, and dll created correctly. So I think it might be related to IDEFixPack, but I am not quite sure.

After 5，select All targe, try it, thanks of your answer.

1.Build project2.dll, a dll file will created, ok 2.apply options with testoptions.optionset. can set teststep.png. 3.Build project2.dll, binary file become exe IDEFix.rar

IDEFixPack will cause Delphi settings error, follow the steps below 1.New a EXE project,Project-Options-Compiler-Save Options 2.New a DLL project in same project group (MUST), Project-Options-Compiler-Apply Options select the options 1 saved and select modify this config 3.DLL will compile to EXE ext instead of DLL ext If no IDEFixPack installed, 3 DLL will compiled to DLL ext
