Hi,
I would like to update a package.
I've distributed a msi with a mst, changes are in the mst.

Now, I've a new mst with new changes but it's the same msi.

Question:
Is it possible to create a msp between 2 mst?
If not, how I can do that?

I don't want to uninstall the first version because a lot of parameters was created after installation and I'would like to keep them.
Thank you for your help.

This behaviour explains why you sometimes find orphan files and/or registry data after an uninstall.

Thank you VBSCab.
After uninstall , registry keys are still installed.
But, the new installation don't know keep this settings.
So, I'd like to do a patch but I don't know how to do that (with 2 mst)?
Have you got an idea?
