Well I didn't get to post the problem/fix before you did (I noticed you used ElementPath instead of ElementId), but I can at least help you a tiny bit with the uninstall...
<Component Id="XXXUninstall" Guid="myGUID" > <util:XmlConfig Id="XXXUninstall" File="[DIRECTORY_PATH_CLIENT]web.config" Action="delete" Node="element" VerifyPath="add[\[]@name='AppCacheModule'[\]]" ElementPath="//configuration/location/system.webServer/modules" On="uninstall" Sequence="1" /> <CreateFolder/> </Component> If I've modified this correctly it should handle the uninstall for you. I remember the first time i tested an uninstall where i had to edit a web.config, got it wrong and removed half my web.config :) James -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/trying-to-add-XML-element-to-a-web-config-file-tp7596447p7596454.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ Slashdot TV.
