Hello,

I am fighting for some days now with figuring out the best update 
strategy and writing samples for updating and/or patching.
Is read the tutorial (http://www.tramontana.co.hu/wix/lesson4.php) 
several times but there are still lots of open questions. Also the MSDN 
doesn't help that much with upgrades and patches.

So my question is what is the best strategy with upgrades. What are 
other developers using.
- Always full install and remove the old version
- small/or minor updates
- patches

Requirements:
- Install and Updates must be redistributable with group policies.
- The updates/patches must run without having the original MSI.
- The latest update must be always be able to update the product, 
doesn't matter which previous version is installed.

Scenario:
- customer installed v1.0
- v1.0 gets patched/updated to v1.01 and installed by the customer
- for whatever reason the customer gets updates v1.01 - 1.19 but does 
not install them (never change a running system ;-))
- now he gets v 1.20 and wants to install it. This update must be able 
to patch all version from 1.0 to 1.19

Are there any examples for a scenario like this? Which would be the best 
update strategy?

Alex
