R : With grass-roots Windows NT 4.0 (that is, without a recent copy of Service Pack installed), the assistant runs correctly, but the Navigator doesn't. .
To verify if it is your case, double click on the icon 
(Generalities about computer algebra) in the assistant's strip (second icon from
the left). This opens a toolbar entitled Alg\Calfor01 (cf. sec. 7.2). Click on the button
Man Util Ros écr. of this toolbar.
If nothing happens, close all programs other than assistant AsTeX and click on the
button Ini Navig of the toolbar . This will
install the more recent libraries required for the execution of navigator AsTeX. In the
case where the button Ini Navig would not function, you can open the folder
Rosetta on the desktop and double click on the icon Install Navigateur
AsTeX (Fig. 2.2). Another possibility is to double click on the program
setup.exe in the directory astexdis\navig of the CD-ROM, from Windows
Explorer.
