Problem with usp10.dll

Hy, my program it's written in Visual basic 2010 vs2010 and use Crystal Reports 2008 engine.

In IDE enviroment I can see the CRw32.exe load c:\windows\system32\usp10.dll and C:\Program Files (x86)\Business Objects\BusinessObjects Enterprise 12.0\win32_x86\usp10.dll  and there are no problems with justify text.

My exe program have problem because it load only c:\windows\system32\usp10.dll.

I can't understand why my executable program load this dll and not other ...

Anyone have some idea ?

Thanks

Filippo
