Custom commands when deploying Windows 7

I got a question the other day on a problem where a person is installing a set of applications during deployment of Windows 7, using MDT 2010. The problem is that one application requires to be run in Vista compatibility mode before it can even be installed, most likely due to a check in the installer for which Windows version is being used, a rather common compatibility issue.

One solution to this is to use Compatibility Administrator which is a part of ACT to create a so called “shim” which makes the installation go through, fooling the application that the OS is Windows Vista even though it is Windows 7. But, how do we get the shim applied during our deployment, which we want to automatic?

It is rather simple, just add a “run custom command” in the task sequence before the application is installed, which applies the compatibility shim to the machine, making the installation run through. Also note that you can run custom commands in the “applications” section in MDT2010, just add the command line to the path field and off you go!
