Sometimes Overwrite Existing Resources

The main choices are:

1. A file resource normally follows various version rules to decide if it should be overwritten.

2. Subject to the component condition, the "RemoveFile" command can be used to clear files/folders. Also see the "RemoveIniFile" and "RemoveRegistry" tables.

3. The "COMPANY.MMH" header will (by default) update the "REINSTALLMODE" property so that files are overwritten irrespective of "normal" versioning rules, if you do not want this then reconfigure this behaviour. A major Windows installer limitation is that you can't be more selective (at a component or file level).

4. One or more custom actions to perform all the update and removal logic.
