[wpkg-users] How to handle unknown uninstaller name?

[Kevin Keane]

I'm trying to create a package.xml file for Aspell and a couple of 
dictionaries.

The problem I am having is how to create the <remove> entry. Aspell uses 
an uninstaller of the style

"%PROGRAMFILES%\Aspell\uninsXXX.exe"

where XXX is a number.

Each individual dictionary gets its own uninsXXX.exe and uninsXXX.dat in 
the same directory. So after installing the English and German 
dictionaries, I end up with files unins000.exe, unins001.exe and 
unins002.exe - or in some cases after reinstalling even unins003.exe or 
higher numbers. Which of these uninstallers goes with which package 
depends on the order of installation. The correct number is listed in 
the registry Uninstall key.

Is there a way to tell WPKG to use the uninstall key from the registry, 
instead of hardcoding the -potentially wrong - name of the uninstaller? 
The registry entry probably needs some "munging" because it is usually 
the non-silent uninstaller.

Thanks!

Attached is the package XML that I currently have, without <remove> tags 
so far.
