modifing app.config file during installation

[Tim Marsden]

Hi,

How do I modify the app.config file for my application during install.
The file is not available when using a helper class or custom action program
until after the install?

Hello Tim,

Thanks for posting, if you are working with VS.Net Setup project and
managed .Net custom actions, the App.config file should already been
installed when the custom action is run.

Please note that we the installer class is executed, the current working
directory is "C:\windows\system32". So you may need to path the target
installation path as the "CustomActionData" into the installer class.
Please refer to the following links:

We can use the following as the "CustomActionData" for the custom action:

/name="[TARGETDIR]\".

I hope this helps.
