I am sure this not is new issue but I stumbled on it today and was curious how others are addressing the issue. I have purchased a sharewear program so when I tried to use is on another logon it prompted me for a serial number. This to me is a bit of a folly as I though sharewhere was licensed to a cpu. While I cannot follow there legal rules I think common sense is that if it prompts each user for a serial number it seems (to me anyway) that you do not want to give the user this type of information. So how do individuals and companies handle this situation? It most likely stores its registration information in the user's home folder rather than a system area. This is not unreasonable. If, after reviewing the license terms, you determine that it is a per-CPU license, you should be able to enter the same registration information for each user. If you are having problems, you should contact the shareware author for assistance. After all, you are a legitimate customer and have paid for it. Craig
