Hi,
I am new to Wix trying to create an installer where certain files are removed
by the uninstaller depending on a checkbox in the user interface. I have seen
some similar questions on the Wix mailing lists, but no definitive answers on
how to get it to work.
Some of the comments I have seen include that it has to be a secure public
property to be accessed by the install sequence after being set in the UI, and
that the feature has to have been installed in the first place to be able to be
removed.
>From testing, it seems that the setting of the property in the UI is

The bits of code being used essentially are:
<Component Id="RemoveConfiguration" Guid="79aba5ff-e091-460a-a212-34448e1460f2"
Directory="MyAppData">
<Condition><![CDATA[REMOVECONFIGURATION OR (WixUI_InstallMode <>
"Remove")]]></Condition>
<!-I have tried a variety of other conditions such as NOT Installed for the
second part, but thought it had to do something to ensure it ran during
installation, not just uninstallation -->
<RemoveFile Id="MyXML" Name="Configuration.xml"
Directory="MyAppData" On="uninstall" />
<RemoveFolder Id="MyAppData" On="uninstall" />
</Component>
<Property Id="REMOVECONFIGURATION" Secure="yes" />
<!-also tried removing this and letting the UI just set it -->
<!-- The control on the modified maintenance type dialog -->
<Control Id="RemoveConfigCheckBox" Type="CheckBox" X="104" Y="162" Width="180"
Height="20" CheckBoxValue="1" Property="REMOVECONFIGURATION"
Text="Also remove application configuration settings">
<Condition Action="hide">ARPNOREMOVE</Condition>
</Control>
Is there something fundamentally wrong with this approach? Is it too late in
the UI to change a property which affects a component condition (due to
CostFinalize or something)?
Thanks,
Edward
