App-V 5 and sequencing platform

Microsoft best practice states that you should match your sequencing platform to your target platform. App-V has always given us an extremely well working platform to avoid that and still does. However, we have a game changer; Extension Points

What are extension points? More integration into the operating system to allow users to use their virtual applications in a manner they expect that it should simply work.

Did you just pop-in a music CD (not really ?) and had the default media player virtualized?

In App-V 4.X that would cause an issue due to the fact that the operating system had no awareness that you had a media player. Autoplay was not a supported extension point within App-V 4.


As you can see there are several possible choices in the above list on what todo when an Audio CD is inserted. If the application is virtualized – in an App-V 4.X environment it would not be visible in the above list.

App-V 5 changed the game and extended the list to support this scenario and much more. However, there is a new found reason of actually doing what Microsoft has been telling us todo all along.

Your sequencing platform should match your target platform.

For Windows 7 64-bit, you should sequence on Windows 7 64-bit.

In App-V 5 this is even more valid as several extension points are not following along if you attempt to sequence on a 32-bit platform and deploy to a 64-bit platform.

    Thanks for blogging about all the App-V 5 tips over the last year. Its been very helpful.

    A few Microsoft docs now include this guidance:

    “Always sequence 32-bit applications on a 32-bit sequencing OS. This includes sequencing 32-bit applications for delivery to 64-bit clients. When sequencing 64-bit applications, they must be sequenced on a 64-bit sequencing OS and can only be delivered to 64-bit clients.”

    To me, Microsoft is saying that the sequencing platform should always match the application (32-bit/64-bit) which conflicts a bit with your advice to always match the sequencing platform with the target platform.

    Any thoughts on this?

      My advice is based on applications that require certain of the new extension points. If your application doesn’t require any of those – the above statements can be followed as you like.
