Hey all, I'm happy to report that we figured out the root cause of the really strange rollback behavior we saw in the .NET Framework setup (described in a post earlier this week) and I wanted to pass on what we found in case any of you hit this issue with a Windows Installer-based setup in the future. Here is a rough outline of the issue and the underlying problem:
The only thing we are not sure about is why the RBS file was orphaned in the registry and on the user's machine to begin with, so we'll have to keep digging into that if we get any additional repro machines and see if we can figure it out. We are going to look into making the next version of Windows Installer smarter about which RBS files it will run when it is removing backup files to try to help avoid this scenario in the future, but in the meantime if you encounter this behavior in any of your scenarios, start by taking a look at that registry value and see if there is any orphaned data that may be causing your setup to rollback.
Hope this helps......

Hi Error1722 - Are you seeing this error during .NET Framework setup or some other product? If possible, can you please use the information listed at blogs.msdn.com/.../help-me-help-you-if-you-have-setup-bugs.aspx to try to collect verbose log files from the failing install so I can try to take a closer look?
