The UseInstallWizard setting is one of the
AppSettings that is contained in the web.config file.
The UseInstallWizard setting is used by installs that want to skip the step by step wizard and instead kick off the single step install process i.e. sites that have manually configured the database connection strings. It's often combined with the
AutoUpgrade setting.
By default UseInstallWizard is set to true. This can be verified by opening the web.config and locating the value in the appSettings section - it will look like this:
<add key="UseInstallWizard" value="true" />
If you wish to stage the install, change this to false i.e
<add key="UseInstallWizard" value="false" />
If this is set to false then instead of starting with the install wizard DotNetNuke will call the install page passing the necessary path through:
http://www.yoursitename.com/Install/install.aspx?mode=install
Note: The install page supports a number of other
parameters.
