    Currently have XP. But, I have heard/read that it is possible to do a clean install of Windows 7 from the upgrade disc. Or is that only possible on a PC?

    If so, how would I go about wiping XP off and then doing a clean install of Windows 7's 64 bit version?

    Thanks I found that after posting :eek:

    Now I need to find out about installing the 64 bit version. I did some searching already but it looks like there could be problems. That Vista was never supported in the 64bit version by Apple, so maybe not 7 either, but I guess that still remains to be seen since Apple is not supporting 7 at all yet. I imagine there is probably a workaround though.

    I'm not sure if this was posted in the linked thread or not, but I found the easiest way is to do a clean install, then while in Windows 7 put the Windows 7 DVD back in and select to Upgrade your Windows 7 install to Windows 7. It sounds strange, but after upgrading Win 7 to Win 7 you can use your upgrade key just fine.

    Yes, but I've read those saying that is was the MBP that could run it. That certain other Macs would have trouble. Both of mine are Intel Core 2 Duo 2.16Ghz, one has 4gb ram (think it really only uses 3gb), and the other 2gb if that matters.

    Simple rule: If you don't intend to have => 4GB of RAM in your system, stick with 32 bit. At 4GB you do get some of the extra RAM lost under 32 bit back if you go 64bit, so there is some possible benefit from going 64 bit.

    There are some issues installing W764 to early 64 bit capable Macs due to the way they boot. However there are workarounds posted all over the 'net.

    So it sounds like I should just stick with the 32 bit version since one Mac has only 2gb and the other essentially 3gb. Thanks!
