Scripting

Ice 91 is only a warning - not an error.

If the following statements are all true, you should usually be fine:

1) All your applications "entry points" (shortcuts, Clsids, extensions, etc) are advertised. And your OS supports advertising.

2) All the above entry points are in the same feature or a "child" feature of the feature containing the problem component(s). If you have captured the installation using a Wise product, this will usually be true.

3) The component(s) have an HKCU keypath that is not likely to pre-exist in any user's profile (no ICE38 errors).

4) The original source MSI will be available to the user the first time he runs the application (in the event that a file needs to be copied to his profile). Bear laptop users in mind too - some people like to pre-copy the MSI to a local folder before installing it.

For "per-machine" installations, the Windows Installer service will repair the broken components the first time the user runs the application (if all the above are true).

You could write a script to verify all these things.
