Valentin,

declare long ShellExecute in "shell32.dll" long hwnd, string lpszOp, ;
                    string lpszFile, string lpszParams, ;
                    string lpszDir, long nShowCmd

ShellExecute( 0, "open", "www.microsoft.com", "", "", 1 )

will launch the users current browser application. You don't have to worry about what browser they use or where it is installed.

>How can I run the Internet Browser(IEXPLORE.EXE) regardless of where it is being installed (C drive or D drive)?
