Wix major upgrade?

The most straight forward way would be to schedule your RemoveExistingProducts after InstallExecute or InstallFinalize. That way the config file is not removed and then installed again (like if you schedule before InstallInitialize). Of course, scheduling RemoveExistingProduct so late means you need to be very careful about your Component Rules.

If not in cases like this I assign the config files to their own components and mark them as Never Overwrite. This way upgrades will not overwrite the file but uninstalls will remove it.

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.
