Software Deployment

It would be done similar to Office 2007: http://www.kace.com/support/kb/index.php?action=artikel&cat=4&id=992&artlang=en

Here are some specific examples:

One thing to note is that you will have to create 2 custom inventory rules if you plan to deploy both the 32 bit and 64 bit versions.

It would be something like this for the x86 install:

RegistryValueEquals(HKEY_LOCAL_MACHINE\Software\Microsoft\Office\14.0\Outlook, Bitness, x86)

More info on this can be found here:http://technet.microsoft.com/en-us/library/ee681792.aspx

There are several ways to get this done as jknox pointed out, but I found the admin install to create a transform worked best. This way I was able to get Office 2010 deployment to a one click operation.

Something to keep in mind, if you want to deploy to a larger amount of systems, it takes a lot of time to copy everything over if you just the kace box.

If you want to do a scheduled upgrade you might want to use a local install repositories (by using DFS or using labels for different locations, ipbased?).

We then loaded a runonce registry key to start installation using a managed installation. 
The next morning your systems boot they all upgrade to office 2010 and you keep installation time to a acceptable amount.
