[wix-users] why does 64 bit bundle install key/value pairs under the 32 bit HKLM/Software/Win6432Node registry key?

[Ian Bell]

You are correct and I should have been clearer.  I was just commenting on
what happens when the same installer is run twice in a row - the first time
installs, the second time repairs/uninstalls.   I was not suggesting this
was a bug or a problem.

Thanks,

Ian

This sounds like the second time you're installing you are not installing
something that has a different version from Windows Installer's perspective.
Remember that Windows Installer ignores the 4th version component. If during
your upgrade testing you install base version 1.2.3.4 and then upgrade to
version 1.2.3.5, then Windows Installer treats it as the same version and
you get the repair behavior you're seeing.
