WIX - Cannot Uninstall MSI Package

Question

I created a WIX installer (using WIX 3.6) that worked fine. I “install” the website in IIS and deploy the database using the VSDBCMD command. The user action of the database is what creates the problem during deletion. It should not actually start during unistall and now during the removal of its failure with an error - "Deletion success or error status: 1603." (From the application log)

So, I now have 2 questions → 1. How can I instruct WIX not to trigger user actions during deletion? 2. How to remove residues previously MSI. Any manual ways to do this?

Thanks in advance!

Answer 1

I had a similar problem when I could not get the MSI package to remove the download and run the Fixit application from Microsoft, uninstalling it for me. You can download it at http://support.microsoft.com/mats/Program_Install_and_Uninstall

Answer 2

How can I instruct WIX not to run a custom action on deletion

To perform a custom action only during installation, you can set this condition for it:

NOT Installed 

How to remove residues previously MSI. Any manual ways to do this?

To automatically remove old MSI installations, you can use the upgrade item with your old MSI UpgradeCode . If you just want to clear some of the remaining files, you can try using a custom action .
