Now that Windows Vista is here, I know a lot of people are going to want to run GAT/GAX and Software Factories on the new OS. While it is possible to run these on Vista, there are some known issues with the June 2006 CTPs of GAT/GAX, especially around installation. As we discover these issues and hopefully find workarounds, we'll be publishing them to the GAT Forum site - there are several there now which you should check out if you're running, or planning to run guidance packages on Windows Vista.
These workarounds are only intended to be a stop-gap measure, and we are currently working on a minor update to GAX and GAT to resolve these issues so everything will work smoothly on Vista. We'll give more details on the scope and timing of this release as soon as we know them.
