x64 Wow oh wow!! Big news! Huge News!!! The MDOP product team just announced the immediate availability of the Microsoft App-V 4.6 beta, the first version to not only support 64-bit clients but also the virtualization of true 64-bit applications:

Today, I am happy to announce immediate availability of Microsoft Application Virtualization (App-V) 4.6 Beta.  At TechEd EMEA we announced our commitment to ship the next version of App-V in H1 2010.  In March of this year, as part of the MDOP 2009 launch, we indicated that the development of App-V 4.6 was underway.  Today, we have reached a major milestone and are a step closer to our goal.

This will be the first version of App-V to support both x64 and x86 Windows platforms.  The primary focus of this release is to enable App-V to take advantage of 64-bit Windows platforms including Windows 7 and Windows Server 2008 R2.  We’ve also made some improvements in the App-V Sequencer such as simplifying the workflow for creating virtual applications and adding the ability to sequence true 64-bit applications, a first to market!  For customers running Windows XP or Windows Vista, you can also use App-V 4.6 Beta and take advantage of the support for Office 2010, 64-bit platform support and additional features in the release.
