Patch transforms applied in a bewildering order

Hi all,

This doesn't seem to be causing an issue as yet, but it's something I really want to understand.

Basically, we have four versions of our product: 1.0 (2.6.0.0), 1.0.1 (2.6.1.0), 1.1.1 (2.6.3.0) and 1.1.2 (2.6.4.0). We're just testing the full and patch installers for 1.1.2.

The odd things we're seeing is that when applying a patch from 1.0 -> 1.1.2, the log for the installer shows that it chooses to use the 1.0.1 -> 1.1.2 patch transform first, which to me is silly as there is a transform from 1.0 -> 1.1.2 it can use. The log is below:

[CODE]SequencePatches starts. Product code: {A9206E66-68A6-4A64-8ECA-F96D2635FB33}, Product version: 2.6.0.0, Upgrade code: {58142252-3B0E-44CA-99EC-F9FB3C4D976E}, Product language 1033

So why does it choose to apply the wrong transform first? I'm guessing it applies it anyway because when it gets to the correct transform, it knows the product version has been updated to 2.6.4.0. I noticed that in the patch designer under the previous setups folder, the order is indeed 1.0.1, 1.0, 1.1.1. Surely this isn't determining the order that Windows Installer runs the patch transforms?!

I've found a solution to the problem, you can find it here: http://stackoverflow.com/questions/11102953/why-does-windows-installer-install-my-patch-transforms-in-the-wrong-order (Sorry for the cross post)
