This installation works fine on one computer. but when i instals this application on the other computer, then no directory is made in the wwwroot directory.... but in contolpanel-> add remove programs.. entry is present showing that application is intalled correctly..... i checked the iis by writing http://localhost ,but i got the error " this page is under construction" .... Can some body tell me what's the problem there and how to solve it.... without uninstalling/reinstalling IIS....
