问题
I have one MSI setup like this:
<Product Id="*" ... UpgradeCode="4207FF3B-5E0D-4311-9DFC-B41AA8DE2965" />
<MajorUpgrade DowngradeErrorMessage="Can't downgrade" />
It works as expected:
- Install product
- Recompile (effectively generating a new Id)
- Starting the new msi file brings up the change view and I can repair or uninstall the product.
Good. But then comes burn.
I have created the most simplistic Bundle one can thing of. I use the standard bootrapper and just add one single MsiPackage:
<MsiPackage SourceFile="$(var.Setup.TargetPath)" />
The problem is that after each recompile I can install the product once again beside the already installed product, without changing anything! This results in duplicate ARP entries!
If I don't recompile and run the bundle exe-file twice, I get the modify setup screen as expected. What can I do to have the same behaviour with burn as I had with just an MSI?
回答1:
Increment the bundle version number and Burn will upgrade the previous version and remove it.
