software setup

Question

Hello,

 

        I have been created software setups many times. But this time I faced a problem. I installed setup in my PC and laptop. It works fine. when I installed setup in client's system with my pen drive.  It installed successfully and creates shortcut on desktop. thats fine. But when I double click on shortcut to open, It opens a dialog box with this message "Please wait while windows configures .....". some loading process occurs and then my software runs properly.

     But when I remove my pen drive and click on shortcut it shows a message: "Please insert CD ROM....." . and software does not work.

Please help me. why this problem occurs in his system only and how to solve it?

 

                              Thanks in advance.
