How to prevent dynamically linked files from being overwritten

I have an upgrader msi project, here's the situation - 

 

1. I have installed my product with fresh installer MSI which has dynamically linked files.

 

2. In that dynamically linked file there's a config file which I have changed accordingly

 

3. For next build I run the upgrader MSI and it overwrites the config file which I have changed.

 

So is there any option, where I should be able to set Not to overwrite such files, which are dynamically linked.

  • Use exclude file pattern (*.config) in dynamic file settings. 

    Thanks,

    • @Thananjeyan_M   That's a great suggestion, but in my product we have older versions as well, where those files doesn't exist, in that case upgrader msi needs to place that file, I can't really exclude that.

       

      I want installer to leave that file if it's already there.

       

      Thanks.
