I have a copy of MS Office 97 which I would like to install on a new pc (which only has XP hence no Word/Excel) with the intention of installing my copy of Upgrade Office 2k. Trouble is I no longer have the key to 97 and now overwritten the program. My cd has an 11 digit code which I thought was sufficient to keep but my pc is asking for a 20 digit code. Does this mean that I have to buy new software? Have looked on the MS website but nothing relates to Office 97. Any advice would be appreciated!
