This component search seems promising! When you mentioned a 'component
guid' do you mean the Product element's GUID or a GUID for any Component
element in the previous version? Hopefully the Component elements as my
Product's GUID is *. My plan is to reference one of the current Component's
GUIDs and change the GUID in this installer so future versions won't trigger
the property. I tried playing around with ComponentSearch but things aren't
working quite as I hoped. I have a Property set like this:
<Property Id='OLD_INSTALL'>
<ComponentSearch Id='SearchForOldInstall' Type='file'
Guid='44738CED-B555-4b28-BA03-12EB50A0D7C1' />
</Property>
Where Guid is set to one of my Component's GUIDs. And I have a Condition:
<Condition Message='Already installed'>
OLD_INSTALL
</Condition>
If the ComponentSearch's type is "file" this is never triggered (regardless
of whether the application is currently installed or not). If the type is
"directory" then it's always triggered. Any ideas?
