Let me make sure I'm following you correctly here. The auto-update
feature of your application downloads a new setup.exe and uses it to
upgrade to the new version *and* it also uninstalls the old version by
locating the UninstallString in the registry for the old version?
Have you defined Bundle/@UpgradeCode in your setup project?
Bundle/@UpgradeCode should be static just like Product/@UpgradeCode is
static in your MSI project. Both of those should be different.
When you properly define Bundle/@UpgradeCode then burn automatically
detects upgrades and uninstall the old bundle for you.
To get the proper upgrade behavior on the MSI itself you need
Product/@UpgradeCode and use the MajorUpgrade element or author
Upgrade yourself. I'd recommend using the MajorUpgrade element.
Once all of this is properly setup you should be able to download your
setup.exe and run it to upgrade (install the new version _and_
uninstall the old version) automatically without needing to find the
old version or anything like that.
