Windows 7: Upgrading to 64-bit Win 7 Pro from 32-bit Vista Home Premium?

Upgrading to 64-bit Win 7 Pro from 32-bit Vista Home Premium?

Hi all!

***First up, mods - if this is in the wrong sub-forum, please move! I wasn't sure the best place to post up :-) ***

Admittedly I feel a little late to the party with Windows 7 (what with 8 being on the horizon) but after several years (!) of plugging away with Vista Home Premium on my laptop (used every day for work), I'm at the point where I need to update it.

Don't have the money to replace it outright, and it's also recently had a new HDD and RAM upgrade, so I'm exploring the possibility of finally upgrading to Win 7 (particularly seeing as mainstream support of Vista has now finished).

From what I understand, a clean install of Win 7 is probably better than an update over Vista (and I am happy to do a clean install as I have all programs and everything backed up), but the one thing I am unsure of is whether I can jump to 64-bit Win 7 Professional with the hardware specs of my machine.

The laptop is an Acer 5103WLMi with the following spec (from System Information):

Processor: AMD Turion 64 X2 Mobile Technology TL-52, 1600 MHz, 2 Cores, 2 Logical Processors
BIOS: Acer V2.70, 07/12/2006

The Windows 7 Upgrade Advisor report seems to indicate that upgrading to 64-bit is possible on a custom install, but the IT tech I spoke to at work says that because System Information lists the System Type as 'X86-based PC' that it can only use a 32-bit version of Windows. Is that correct?

Hello BiddlyWiddly, Welcome to Sevenforums.

If your processor is a 64Bit, then without any doubts it can run Windows 7 64 bit. And I am pretty sure your processor is a 64bit.

Windows 7 Pro X64 SP1

A clean install of an OS is best. In going from 32 bit to 64, it's also the only path permitted. (An upgrade-in-place is not supported.) Also, Microsoft does not permit an upgrade-in-place from Vista Home Premium to Win 7 Pro, even at the same bit depth. (A Custom installation is permitted.)

Your CPU supports 64 bit instructions. The "X86-based PC" is reported from a 32 bit OS, regardless of the capabilities of the hardware.

It appears that Acer doesn't offer any 64 bit drivers for the notebook. That may make going to Windows 7 awkward, especially if any of the hardware (like the graphics) requires a custom installer. I expect that it will be possible, but it may require more effort.
