Installing HP Scanning Software from Norton Desktop If you are running MicroSoft Windows (3.0 or 3.1) using Norton Desktop as the shell, you must change the shell to be PROGMAN.EXE before installing the HP Scanning software. How to change the shell: - Run Windows' NOTEPAD and open the SYSTEM.INI file which is in the "WINDOWS" directory. - In the [boot] section you will find a line that reads shell=ndw.exe - Make a copy of this line and insert a ';' as the leftmost character in the first copy. - Change the second copy to read shell=progman.exe - Restart Windows (Exit then type WIN at the DOS prompt and press ENTER)
