[wix-users] Msu Packages not cached

[Neil Sleightholm]

I have an MsuPackage element that downloads a package from the Microsoft download site, the package has a RemotePayload and it all works as expected except that the msu package is not cached. I have tried setting MsuPackage/@Cache to "yes" and "always" but it is downloaded to "C:\ProgramData\Package Cache" and then at the end of the install it is deleted. This means the next time an update is installed it downloads the package again.

Is this by design or is there something I can do to force to be cached?

The package is question is KB4022719, I suspect the root of my problem is that I don't have MsuPackage/@InstallCondition as I cannot find anyway to check whether this is already installed.

Regards
Neil
