[wix-devs] 6772 - ExePackage ARP entry

[Sean Hall]

"My" scenario is multiple versions of the same product use the same ARP
key. When the bundle that has that package in an ExePackage is installed,
the ExePackage should only be installed if it's missing or there's an older
version. When the bundle is uninstalled, the ExePackage should only be
uninstalled if that exact version is installed.

If you do the second part by itself, then it gets uninstalled when there's
a different version. The first part is also necessary.
