Problem solved. All it took was adding [INSTALLDIR] to my module.wxs, e.g.
<util:XmlConfig Id="ConfigSectionCachingAdd" File="[INSTALLDIR][CONFIG_FILE]" Not sure what those NOT FOUND errors that Filemon was reporting at the start, and I'm still struggling with the inner workings of XmlConfig, but at least it finds the file now :) cheers si ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
