I have everything working nicely -- except that my installer won't replace an older version of my product if it finds one installed.

I assume I have to configure the Patch button in each component's Configuration pane.

Or do I simply have to write a preinstall script and remove older versions of components myself? It seems odd that the documents don't say anything about this, although Stephane Sudre's old How-to article about an earlier version of PackageMaker says as much. I guess that would provide the flexibility needed to deal with different names and configurations in older versions of the product. But how does that fit in with the ability to allow or prohibit downgrades using a simple checkbox? If PackageMaker/Installer can tell by itself how to prohibit a downgrade, why can't it deal by itself with an upgrade? And then what is the Patch button for? -- Bill Cheeseman - bill@cheeseman.name Quechee Software, Quechee, Vermont, USA www.quecheesoftware.com PreFab Software - www.prefabsoftware.com _______________________________________________ Do not post admin requests to the list.
