[wix-users] Strategy to migrate to WiX from another MSI build tool

[Hoover, Jacob]

Your ARP entry for the InstallAware package probably isn't the MSI but rather an uninstaller exe.  

My guess is you need to detect the entry that is visible in ARP with a burn bundle, such that you can invoke their uninstall exe with a BA before entering a MSI transaction.

Why it doesn't work by using the MSI's upgrade code?  More than likely they didn't add their source path to the registry as they didn't want you to be able to remove the MSI without removing their EXE entries.

Subject: [wix-users] Strategy to migrate to WiX from another MSI build tool

Hello Everyone,

We are currently using InstallAware to create our MSI and EXE for installation. We would like to move to WiX. I have build simple MSI package and provided update code from existing package.
During executing new MSI package there is an popup window complains about not able to find MSI for UnInstallation. So I am assume that Upgrade code is working but Windows could not find original MSI. If I start un-installation from control panel old product beeng removed successfully.
Any hints how to Uninstall existing MSI before install new one?

TIA
