[WiX-users] How to change the installed config file after msi setup

[Nan Z. <na...@ex...>]

Hi, 

I am not sure if this is a wix question. But I prefer to get some advise from the setup expert here. 

I want to make an msi to install files (application.exe and application.exe.config) into Program Files Folder, and then from msi to launch another application to modify the application.exe.config file. However, I found my installed folder is "read only", so the user will get "access denied error" when modifying the config file. Is it possible to make the folder (or the config file) to be writable? Or is there any regular rules for this scenario? 

Thanks a lot, 

Nan
