Hi J, Yes this is possible. Are you using just an MSI or do you use a burn bootstrapper?
In case of an MSI you can define a property that you pass on the command line, similar to INSTALLDIR=... You can create your own property say UPDATEXML=<value> where value can be yes or no so something like that. In your component that executes the xml update (or your custom action) you can use the 'condition' facility to let it run based on your command line supplied value. For custom actions you can use the format: <custom action ......>UPDATEXML="yes"</custom> For components you can use the condition tag: <condition><![CDATA[UPDATEXML="yes"]]></condition> But check the documentation for exact syntax.

Subject: Re: [WiX-users] XMLConfig updates only from command line Also the command line parameters do update the config file. Just wanted to be clear that the XML config file should only be written to when a command line parameter is used. Thanks again for any assistance.
