[wix-users] Wix Bundle (per user) Upgrade uninstalls a per machine MSI

[tkdgirlmona@gmail.com]

I am running into a problem with the upgrade of my Bundle installer (which bundles a mix of per user and per machine MSIs). I'm trying to do a major upgrade where 2 per user MSIs have been upgraded. Some other MSIs have been unchanged. 

Most of the upgrade works successfully. However, one of my unchanged MSIs (usb_support_installer for reference) gets uninstalled. This MSI happens to be a per-machine MSI. I see the following in my log files: 

in my logs 
"[20C8:200C][2016-09-28T15:54:06]i000:  PlanPackageBegin 
[20C8:200C][2016-09-28T15:54:06]i000:   PackageId = usb_support_installer 
[20C8:200C][2016-09-28T15:54:06]i000:   State = Present 
[20C8:200C][2016-09-28T15:54:06]w322: Skipping cross-scope dependency registration on package: usb_support_installer, bundle scope: PerUser, package scope: PerMachine 
[20C8:200C][2016-09-28T15:54:06]i000:  PlanPackageComplete" 


and then further down in the logs 
[20C8:200C][2016-09-28T15:54:06]i201: Planned package: *usb_support_installer*, state: Present, default requested: Present, ba requested: Present, execute: None, rollback: None, cache: No, uncache: No, dependency: *None* 

This seems to suggest that my "usb_support_installer" package is not considered a dependency and gets uninstalled once the previous Bundle version is uninstalled. 

Sure enough, I see this in my logs for the uninstall of the previous Bundle version 
[1D4C:15A0][2016-09-28T16:45:25]i301: Applying execute package: usb_support_installer, action: Uninstall, path: (null), arguments: ' ARPSYSTEMCOMPONENT="1" MSIFASTINSTALL="7"' 

Wondering if Burn supports per user Bundle scope with some per machine scope packages? Wondering if I need to do something additional to handle upgrades of such bundles/packages? 

Appreciate any help 
Thanks
