But wait, downloading software from other sites can be risky. So I should caution the user to use official channels only. Let me check who is the official developer. From previous knowledge, POM was developed by Professor Larry J. Gitman and others, but later on, POM for Windows might be associated with Pearson Education or another educational publisher. QM for Windows is part of the same family. The official website might be http://wps.prenhall.com. Or maybe another site.
