How to query a MSM version installed on the PC

Hello,

I have a common apps distributed as a MSI and as part as a MSM incorporated
into others MSI.

Since several packages can include the MSM I need to find out the version of
the MSM when to the user installs the MSI. There could be a case where the
MSI in an older version compared to the MSM installed.

Is there a way to get the MSM version on the System without querying the msi
file? Maybe with the module signature propertie ?

For example the "WMIC product get" cmd on the command line will return all
the installed MSI with the product code and version info. But it won't return
the MSM installed.

Any help would be appreciated.

Thanks,

Minh

When a merge module is merged into an MSI it loses its identity so there is
no notion that there is some version of a MSM installed on the system. It's
just shorthand for a bunch of components. The only way to figure out what's
installed it to look at the file versions of the components from the MSM.
