I would like to get a discussion going on the possibilities or relevance this might have for OEM. Or just have a general discussion, do not know about others but I would like to know more Server SLP Keys, compatibility between x64 and x86 systems. Example (shortened for relevance) from Overclockers: Q/ Can I use the same CD Key Vista 32 Bit OEM on Vista 64 Bit OEM I have a PC running a 32 bit OEM copy of Vista Ultimate. Anyway I wanted to know if I could use that CD Key for a 64 bit Vista OEM install? A/ Sure can.. Used x86 keys with x64 plenty of times before.. No probs with activation at all. Qualification/ Just to make it clear, "officially" you have to uninstall the 32-bit version before using the key for the 64 bit install...but you can install both at once. Re: Another Thread same topic Answer A/ Why all the misinformation? The Dell OEM keys work perfectly with x64. My call to the Dell "service" reps in Mumba^H^H^H^H^H"Sydney" confirmed this, but it was up to me to get my own media. MS licencing rep at the last TechEd seminar they held over here confirmed the same. Answer B/ Yep, you can use the same key for 32 bit and 64 bit. They are interchangeable. I've done it several times with retail and OEM. _____________________ If you would like to contribute. What do you know works in regards to 32-bit systems being activated with its counterparts OEM 64 SLP Keys?
