This is a strange request soI'll give a brief explanation. i am abroad on business, my 64 bit laptop (with Vista) packed in and I was given a Windows 7 Pro 32 bit OEM disc by my IT support to help rectify the problem. I have now purchased a (genuine, I may add) copy of Ultimate and have the product key. Will entering the Ultimate product key automaticaly unlock the Ultimate features or do I need to run the disc and install again?. I'm concerned about overwriting my settings and documents if I change from 32 bit to 64 bit.
