Windows doesn't actually use that uninstall string for MSI products - it just uses the ProductCode and calls the appropriate MSI API.
On the subject of whether an uninstall succeeds or not, if it doesn't you'll see an error and a rollback (although there's an assumption here that any of your uninstall custom actions return error results if it matters). I'm not a UI expert, but I believe there is a UI principle along the lines of "stop telling me when everything works all the time - just show me errors I need to see". So you don't get a messagebox saying "all your files were copied" when files are drag'n'dropped, just when something fails. The uninstall is treated the same way. I'd hate to be drowned in a sea of "Yes it worked ok" messages.

Subject: Re: [WiX-users] Uninstaller screens Might be possible using a custom UninstallString in the registry. http://msdn.microsoft.com/en-us/library/aa372105.aspx How you would overwrite the generated one (msiexec /x [ProductCode]) written during the install process is a good question though. Might be possible using a Custom Action scheduled after RegisterProduct but I wouldn't bet the farm on it. Highly doubt you could do it using just a RegistryValue.
