Instalation problem

Question

hai all,

           I have create one application in .net 2008 which will write and read one xml file namely stockprices1.xml

           Than I have create setup file for this application.when I run this application after the instalation it give the error like

            "Access to path c:program files\application\stockprices1.html is denied"

           It will work work fine if I install this other than program files.

           But it is installed in program files means it will show the error given above

           

           Is there any solution for this?
