BASIC-MSI: Is it possible to exclude installed merge modules during uninstallation from deinstallation?

My msi setup installs some MMs.

During deinstallation are this also uninstalled.

Is it possible to rewrite my setup to preserve MM on customer PC after removing main setup?

Many thanks

Once the module is merged and the project is built, the components in the merge module are part of the whole installer. They are not separate.

The only way to prevent them from uninstalling would be to mark the components in the merge module as permanent.
Alternatively, you could create a prerequisite instead of a merge module.
The prerequisite would install prior to the main installation and remain on the machine if the main installer was removed.
