Dell :: Wont Support 64 Bit Os Since Mine Came With 32 But Its Listed

i went onto the chat to request myself a copy of the 64 bit edition of windows vista home premium since i just want to have it in my collection. I upgraded to vista ultimate 64 bit but having home prem wouldnt be bad.

Anyway. the dell person told me this:

Quote:

"It appears that your system originally shipped with Windows Vista32©, per the OEM contract with Microsoft, Dell will only provide support for the factory-installed Operating System. If the Operating system is changed from what was shipped form the fact"
&nbspory, you will need to contact the specific software vendor (IE: Windows/Microsoft or ubuntu/Canonical Ltd) for any operating system support. Dell will still provide warranty support for the original hardware configuration only. For further information pl

Now according to this thread:
New 64 bit Vista option for 1330--have to have driver support!

The option for 64 bit is on the website. So if my system originally came with 32 bit and they now have 64 bit listed, wouldn't i be eligible for support on the 64 bit version of home premium?

I mean if they are offering it, then whats the difference if it came first installed or not?
