[wix-users] Install initial config file but none after that unless version updated

Seems valid to me, however I haven't used the NeverOverwrite attribute myself.  I can't think of a time where I couldn't just use an XmlFile CA to add or remove options from the config file as the application evolves.

I've set the Component Id NeverOverwrite and Permanent properties to Yes. In the future, If I need to overwrite the file, I'll just change the NeverOverwrite to No. That seems to have done the trick for me. Please let me know if there are shortcomings to this approach.

<Component Id="EDI_Management.exe.config"
Guid="a69977a4-1a35-4aa7-a23d-a12bcc75ace1" NeverOverwrite="yes"
Permanent="yes">
  <File Id="EDI_Management.exe.config" Name="EDI Management.exe.config"
Source="$(var.EDI Management_TargetDir)EDI Management.exe.config"/> </Component>

Regards,
Johnny

Config file is XML, so you should be able to use WiX CA's to update it via XmlFile. I'm fairly certain it is safe as in it won't trigger Windows Installer into thinking the user modified the files. 

Depending on when you schedule RemoveExistingProducts, you could read the desired values before removal of the existing and then write the values after install of the new.  It may be possible if REP is scheduled later that the file would just stay, but I forget the rules behind a non-versioned file. (IE, is it just the last modified time matching that lets WI skip the file, or would it also hash.)

As for adding another parameter, I'd do that with a XmlFile CA as well.

I need to install the application.exe.config file when the application is first installed; however, after the first installation, I want to manage the updates to the config file based on the version number of the file. How do I accomplish this?

 

I put connection string information in the config file. So, I don't want to overwrite the user's connection string information each time an update is installed but I would like the option to overwrite the file should another parameter be added to the file during a later update.
