Does anyone know if 32 bit software will run OK on a 64 bit computer with Windows 8 - 64 bit?

Also which version (32 or 64 bit) is likely to be pre-installed on a new computer after W8 is released?

Help much appreciated

Hi,
Obviously it will run Ok.
Win7 32 bit software run perfectly on Win7 64 bit but not vise versa.

You'll find the 64-bit version installed in most cases (the same applies to Windows 7). Really there are very few reasons why you would want to use the 32-bit version instead of the 64-bit version.

The 32-bit version is most notably going to limit the usable memory in your computer to 3 to 3.5GB even if you have more installed. This is a limitation of the 32-bit architecture.

64-bit Windows can run 32-bit applications just fine.

Its obvious that a 32-bit software will run and perform better in a 64-bit computer. Other than that its very compatible and works freely. There is no if and but case regarding this thing. However a 64-bit software can't work in any of the state in a 32-bit computer.

You are wrong. The performance will be the same, a 32-bit program isn't going to be able to suddenly take advantage of the added features in the 64-bit architecture. However since you can have more memory in the computer you can run a lot more 32-bit applications at once but beyond that there is no performance difference for 32-bit applications when running on a 64-bit OS.

Some 64-bit applications can run a lot better than their 32-bit versions such as graphics programs, crypto or any other math heavy programs. Or programs that can benefit from using a lot more memory.

Having 8+GB of RAM can be really nice these days given how cheap memory is. On my home computer I have 16GB of RAM and although I rarely use more than 30% of it, Windows uses the rest for the program cache so all the programs I use load pretty fast which is nice.

I must confess. Actually I didn't marked my own words, but in real I didn't meant that. I was also trying to say that obviously a 32 bit software can perform in a 64 bit OS and yes of course more 32 bit applications can run on the computer depending upon the memory.

I suggest 32bit software run and compatible good on 64 bit computer
