This is an honest problem. A friend had a problem with his PC, I thought best rebuild it. I ran Aida32 and got the report of what the PC was made up of and downloaded all the necessary drivers. It was sold without a windows disk (Win98 SE) but I have it and the report gave me his licence key. It didn't work! The Aida report tells me that it is Win98SE and lists the licence key but they are incompatible, how can this be?
The CD Key for Win98 can be found in the registry. I can't remember where though. I have only one 98 machine left now, and its in bits. If I have time I will put back together and find where the key is later today. Unless someone posts the answer first.
This may be no help to you at all but, it is a condition of selling/using Windows operating systems that a sticker stating the CD Key or Product Key is firmly attached to the computer case. This sticker is supplied by MS with all copies of their Windows systems.
Note that this key is NOT the same as the licence key which, it seems, you are trying to use.
Have you had a look all around the case (including inside?)
Thanks for the responses It is I believe called Product Key and is clearly identified in the Aida32 report - it is a series of 25 alphanumeric characters in 5 groups of 5. I know that a product key for Win98 will not work with Win98SE and vice versa, the point I am making here is that I was amazed and confused that a Win98SE product key doesn't work on a different Win98SE CD.
