A friend has gone on holiday and asked me to install above on dual boot with Vista. No problem , but they did not have reg key (s) on receiving box of subscription DVDs, including Office & Windows 7 etc. Previously they has Partner discs from Microsoft for Vista, and reg keys in the box. I have loaded the system but the message on Windows 7 mentions register within 30 days... will there be a request for the registration key, as well ,to be confirmed ? Perhaps they have to log on the the Partner program to get the keys ?
