I might buy a new computer soon, and I'm thinking about changing to Win XP 64 (from formerly 32). Now the problem is that I use my computer for several purposes, Chess being only a hobby. So my old 32-software must run on the new system - else I would need to stay with 32. Anyone got experiences with 32-software running on XP 64?

Most of 32-bit applications should run just fine. If application uses partially 16-bit code, then it will not run.
According to my experience there are more problems with games, than with office software or other business applications. Best way to be sure, is to check the compatibility of  every single application that is essential for your needs. If some important applications will not run under 64-bit OS, then you can try dual booting.

I have never found any  32 bit applications that doesn't run OK in 64 bit so long as you download the correct 64 bit drivers - all the standard office type applications run fine with it.  However just to be on the safe side I have been running a dual boot set up for 2 years now. It is easy to do and I have had no issues. Basically you create a spare partition on your hard disk (or use a second hard disk) and install 64 bit Windows on it. Then when you boot up you are given the choice to log into either 32 or 64 bit. As I spend 95% of time using 64 bit, I made the partition that holds the 32 bit system small so as not to waste space.

There are a very clear set of instructions for doing this at this site (don't forget to find the little orange "next page" at the bottom as theer are several pages, but it is easy to follow):

It's not just driver issues. Some 32-bit programmes won't actually install, e.g:

- BBC iPlayer does not install
- Channel 4 VOD does not install

as just two examples. The installers don't recognise XP X64 as XP at all, and just quit saying that you must be running XP in order to install these programs....

That is not correct - I have installed BBC iplayer on my 64-bit Vista system and it works perfectly.
I have not had any problems running 32-bit programs - however one minor difficulty is that some software (e.g. Adobe Flash) will not run in a 64-bit browser - this is not serious as it is perfectly possible to have IE7 in both 64-bit and 32-bit available, but it is an irritation.

You didn't listen to me. This thread is about XP X64, not Vista

BBC iPlayer WILL NOT install on XP 64-bit. It WILL install on Vista 64-bit

From BBC website:
"Please note that 64-bit Windows XP and Windows XP Media Centre are not supported. "

I actually think XP X64 is a bad choice. I would go with Vista x64 every time.

    Vista is over rated\bloated even with the latest service pack it is still slower than XP64 ... In fact if you google `microsofts next OS` you will find reports of a new OS as early as 2009 (SharePoint, Fiji, Vienna or something similar and will prob be WinFS) simply because of how poor Vista is thought of

With Vista you either generally love it or hate it. Many people think it is great. All you hear about is the negative stuff. Yes I read the stuff about the new OS. let's see how many years late it will be. I have both XP X64 and Vista X64. Give me Vista X64 any day. Running chess programs, Vista is the same speed as XP - maybe a 1 or 2% speed difference, nothing to worry about

I have Vista 64 and wasn't able to install older versions of Mathematica and Acrobat.  I used to use Ad-Aware also, and there is no 64bit compatible version available.  Before deciding on an operating system, consider what software you may have to replace.
Parent - - By BigBen (****) Date 2008-05-01 11:40
    I do agree some love it others hate it although I know more who hate it lol :) ... Vista eats memory and was very slow copying data from HD to HD although I do believe a lot of the probs have been at least addressed with the service pack and certain hot-fixes ... I just went to iplayer website and iplayer runs fine on XP64 ... The best thing about Vista is ( have the 64bit ultimate version on a another machine) .... I think is maybe media centre and Networking ...

Not only is it software you have to think about replacing it is also hardware especially if you use the 64 bit version ... of course we could prob end up saying all this again for the new OS when it appears lmao :)

iPlayer runs fine as a streaming service only, as with Linux etc, but the quality is low. You simply cannot install the application itself to have the high quality downloads, as you can with XP 32-bit or Vista 32 and 64-bit. BBC explicitly state that XP X64 is not supported, and they are correct, I tried to install it anyway and the instalaltion failed becuase it didn't recognise the O/S. Anyway I'll just install it on my Vista x64 box instead :-) problem solved in that respect. Channel 4 VOD also installs on Vista X64, but not XP X64

More like someone failed to provide a more specific error message. It takes some stupidity not to recognize XP x64 as XP.

I have Windows XP pro 64 and Ad-Aware 2007 runs fine - I just did a definitions update and scan. Maybe you need to update your version ?

Parent - By Mark (****) [us] Date 2008-05-01 13:29
Thanks Mark.  The 2007 version of Ad-Aware does not work with Vista 64, but I just checked and the 2008 beta version is now available for download and I understand that does work with Vista 64.  I'll give the beta a try.
Parent - By Ray (****) Date 2008-05-01 13:34
Well it is a different kernel, based on Windows server 2003 I understand. This is probably why. But you're right, I wouldn't mind betting that if it actually installed, it would work. Sky Anytime works fine for example... just Channel 4 and BBC VOD applications where the installer doesn't recognsie the OS. Haven't tried ITV
Parent - By Mark (****) [us] Date 2008-05-01 13:13
I didn't have any hardware issues with Vista 64.  Printer and scanner worked fine.  Also, with 4 GB ram and a Q6600 everything runs pretty fast!  I'm still anxious to get the mp version of Rybka to see how that runs!
Parent - - By Kapaun (****) [de] Date 2008-05-01 18:25
Thanks everybody for answering. Well, I guess, since I won't have the possibility to really check it, it will be XP 32, then...

How about dual boot (XP 32 - XP X64), then? :-p
Parent - By Ray (****) Date 2008-05-01 19:39
Definitely, dual boot is the best of both worlds. No Rybka owner should deny themselves the performance boost from a 64-bit OS !
Parent - By atila [bg] Date 2008-05-02 07:26
you must buy win xp 64 professional with SP2 ,and wow 64 emulator,then almost every 32 bit program will be runing on you PC !
