How can I build a multi instance application?

How can build an application (exe file) that can be running in multiple instances (like notepad)?

I select the vi properties.execution.reentrancy.preallocated clone reentrant execution but after building the application, the exe file can be run only into one instance. Double-clicking on the exe file for second time don't open a new instance.

If you add the line allowmultipleinstances=true to the EXE's INI file under the application's section, every call to the EXE will create a new instance. Note that if you use shared resources (hardware, files, etc.), you will have to account for that.

It works!

Thank you.
