This thread has been really enlightening. Thanks everyone for the information. I had this issue a little while ago, with VS building against one version of the runtime and the merge modules delivering another. After a lot of searching online I finally found the code snippets to get VS to build against the latest version. I then had to go and update all our projects, including some 3rd party libraries. We've just come up foul of this again when my boss added a new project which didn't run properly because it was missing this special magic. It sounds like the policy files are pretty much required when deploying the VC runtime as this issue is really hard to track down. It certainly took me long enough to find a work around, and this thread has just shown me that I should have been including the policy files all along. I think the How-To guide in the WiX docs should definitely be updated so that they don't tell the reader that the policy files aren't needed. Actually, they say "There is generally no need..." However, since the update to VS that updated the merge modules, I don't think this is a fringe case anymore.
