Hi folks!

I have a problem with cumulative patches. For example, I have myProgram.msi and two patches to it, lets say a.msp and b.msp where a.msp is generated earliler. The problem comes, when user just downloads patch b.msp without patch a.msp and runs the patch.

Is it possible that patch b examines system and if patch a isn't installed, it won't install and notifies the user to install patch a first. Better solution could be that patch b includes all changes made by patch a. This should be made without changing version number?

Can anyone help me?

Using MSI 3 you can do this with patch sequencing. This is one of the main improvements in MSI 3.
