I am using Wix to install a windows service. The service will need to run under a non system/service account that is set up by the user.
Is it possible to have it prompt for the username/password for the service login?
WiX doesn't (or at least didn't) have anything nice out of the box for what you are looking for. Best option that I am aware of is to roll-your-own.
