Specs: Microsoft Windows XP Professional, 3 GHz / 3582 MB
Hello,

I just ordered my Windows 7 retail DVD, i will be getting both 32 bit and 64 bit OS within the box, my questions is.... would it ok to install the 64 bit OS will all my software work with this? i know it is a difficult question to answer seeing as you dont know what softwares i run, however i have seen on many machine under task manager processor with * before them sugessting that they are running is 32 bit mode.

for example i have windows 7 64 bit installed on my work laptop, there are several applications we use (bespoke) which are running with *process_name 32bit, so does this mean that i should be ok running the 64 bit OS, will the software automatically be able to decide weather to run in 64 or 32 bit?

Thanks for any input you can provide..

Bunty.

64-bit will run both 64-bit programs and 32-bit programs.
32-bit will run both 32-bit programs, and 16-bit (old Windows 3.0) programs.

Most 32 bit software will run on a 64 bit OS, but there are exceptions. If you are contemplating a 64 bit OS you should check to be sure your important applications are compatible.

Some applications will not work for technical reasons.

Some software manufacturers sell both a 32 bit and 64 bit versions, the latter at a higher price. If a 64 bit OS is detected the 32 bit install will fail.

Some 32 bit applications use a 16 bit installer. Except for some well known installers these installations will fail.

If you still work with 16-bit programs, why bother with Win 7 ? Stay with XP.

1st run the windows compatability app, from microsoft it will tell you what will and will not run with win 7 , what drivers will need updating and what programs you can/cannot use..takes a few minutes but will really save you pulling your hair out.

if your system can run x64, then clean install 64bit as a second OS, load your proggies as you need them, and if needed find newer better proggies to replace anything that will not run in x64, or under compatability

but as stated before most 32 bit proggies will run under 64 bit OS..

Unless you have more than 4 Gig of ram the 64 bit would be useless.

Thank you everyone, ok i downloaded and ran the update advisor and apart from some apps that i have written myself (the advisor could not advise on these) everything else passed. However i have Visual Studio 6 which i want to install so will do some in 32 bit or XP compatability mode. thats the only app they advised could cause issues. But its no bother.

Thanks for the help and advice its been very helpful. i think i will give 64 bit a go and see how that works out for me, all my data is on a separate drive so there is no loss with reformatting and reinstalling windows on my main HD if needed.

Awesome work guys/girls thanks again :)

Hi,

I installed my Windows 7 64 bit last night along with all my applications (i downloaded the latest drivers for my motherboard and other hardware) and everything installed seemlessly. Very impressed so far with the performance, i currently have 4gig DDR2 memory from curcial ballistix range, might consider uping it to 6 just for the fun of it :)

Just wanted to thank everyone for their advice and help it is as always very much appreciated :).

4 gb should be all you need, check your system performance, as your using your machine, no point in having 6gb if your not even using the 4 you have..;-)

If you can add another 2 GB RAM, you may totally disable pagefile.sys, which is an unnecessary component for those with lots of RAM. You can even try to disable it with the current RAM amount and see if your computer runs fine without it.

I have mine already disabled with 8 GB, but I do not deal with very large files. By the way, I have this much RAM for the fun of it. I do not do things that require large sums of RAM. When I look at task manager any time, I have always more than 5 GB free.

hahah thats brilliant loads of spare RAM for no reason, yeah thats typically what do usually, have more than i actually need of everything, and in fact i will add more RAM, because at some point i will be using my PC for video editing and converting so it should be usefull. In terms of page file, well ialways install a small harddrive and move my PF to that drive. Makes my pc run much more quicker than having it on the same drive as windows. im loving win 7 at the moment, miss my xp look and feel though. Will get used to it i supose.
