My computer was hit by a virus and SuperMemo reports integrity problems. What shall I do?
(Peter Cool, The Netherlands, Nov 9, 1998) Question: I have installed the help for SuperMemo 98 but it won’t work. After installing the help file and hhupd.exe I see after calling help the hourglass-icon (for a short time). After that nothing happens. Answer: You need to install the HTML viewer (hhupd.exe) over Internet Explorer 3.0. CHM format has been developed by Microsoft and it requires Internet Explorer to be installed on your computer.
