I have a new PC with Windows 7 Home Premium installed.

Can I run my 32 bit software on this system (example Windows Office SSL) or must I buy new 64 bit examples (This would be very expensive for me).

Another way of asking the same thing: Is there a way to invoke a 32 bit compatibility mode for older software?

Thank you

generally there is no need for 64 bit application software on a 64 bit system. Only hardware drivers need to be specific 64 bit versions, but when the new PC came with W7-64 preinstalled this should be no more issue to you. Your system still will benefit from the much bigger memory space, which under 32 bit systems was limited to 3GB.

There is also no compatibility mode necessary. MS Office 32 bit versions for example install without any question on a 64 bit system. You won't notice any difference. Sometimes though compatibility mode is necessary for other reasons like hardcoded XP Style pathes and similiar.

The above is not true for some specific programs, that operate rather close to hardware, like some virus scanners, network clients, etc. But this has to be checked case by case and usually allows only the instalaltion of the proper version. If you are uncertain, you can post a list of applications in doubt and we can check.
