Keep settings during upgrade

[maurosturaro]

I release a new version of my product every 2 month, so users want to launch setup and click next,next,next (I'm adding a Finish button ).

But...
How can I keep the same settings (folders, features, and user input) of the previous version ?
I've start to put each variable in a registry entry at the end of setup script, reading it at the begin.
But it sound a not so nice solution, expecially for the selection of features.
Do you have a better and more Scripting Aware solution ?

Tanks.

Fraid not - this will have to be something you write specifically for your own product.

Solutions:
- Store in registry
- Store in INI / XML file in your application directory

Can't be done in application directory becouse the new setup dosn't know where the previous version was installed.
the only way is register or some fixed folder.

but...

4 days after your answer the new version 6.5 has a specific function for this!
and it works better , so I'v discard my work and replaced.
