MSI diff on packages to create patches?

This statement is based on some faulty logic and whoever uttered it is blowing smoke out the proverbial. There is every bit as much risk from a patch install as what there is from a full installer - if the testers have no faith in your build/release process then both need to be tested fully. The msi is just the packaging a full install or a patch install can both change the whole system.

If the testers want to come up with the argument that "with the patch, the file abc. Dll has not changed so we don't have to test the functionality in it" then you can argue that that thinking is incorrect - if the code using abc. Dll has changed then abc.

Dll may exhibit different behaviour.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
