Calling exe via windows service in C#.net(windows 7)

Question

Dear brothers/Sisters,

i have created a window service in C# .net to call an exe(my application).
i have no problem if i install my service in XP OS.the service is popping up my application.
but i installed my service in windows 7 OS when my service pops up my application,windows 7 pops up a message like  "this application is not fully compatible".the message has button to view my application in different window which is not related with desktop(header text of that window  is "InActive serive detection").

can any help me to resolve this problem

thanks
