Blair,
Yes I was speaking of the installer's command line parameter. I have been reading over some blogs and examples and I want to make sure I have this correct. I can use the session to access the command line parameters and then assign those to Wix in this kind of structure <File Id="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" Name="app name.exe.config" LongName="app name.exe.config" src="app name.exe.config " Vital="yes" DiskId="1"/> <XmlFile Id="configparameters" Action="setValue" ElementPath="/configuration/userSettings/a...@key='project']/@value" File="[INSTALLLOCATION]\app name.exe.config " Value="[PROJECT]"/> .If I understand this right, the command line parameter would look like. setup.msi PROJECT=MyProject .and the msi will make a change to the project property value app name.exe.config file. <?xml version="1.0" encoding="utf-8" ?> <configuration> <configSections> <sectionGroup name="userSettings" type="System.Configuration.UserSettingsGroup, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=zzzzzzzzzzzzzzzzzzz" > <section name="app_name.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=2.0.0.0, Culture=neutral, PublicKeyToken=zzzzzzzzzzzzzzz" allowExeDefinition="MachineToLocalUser" requirePermission="false" /> </sectionGroup> </configSections> <userSettings> <app_name.Properties.Settings> <setting name="project" serializeAs="String"> <value>MyProject</value> </setting> </ app_name.Properties.Settings> </userSettings> </configuration> I read in one blog that stated an msi file only has access to things like the command line durring a non-defered phase and it can only modify files during a defered phase.did I miss something?
