--- Comment #17 from Lukas Jirkovsky l.jirkovsky@gmail.com 2008-12-17 03:14:04 --- This bug doesn't depend on version from which you're upgrading. Upgrade installer contains complete DPP. When it's run, it only checks for key DPP in registry (so if you create this key, you don't need to have installed DPP). If this key exists, it will extract all files and then run installer.
I'm upgrading to DPP 3.4.1. Soon I'll test it with a new wine version.
