I have the following in my main WiX wxs project file: <MajorUpgrade DowngradeErrorMessage="A newer version of [ProductName] is already installed." />
I then installed a newer version of my software and then installed an older version and instead of getting the error message that a newer version is already installed I get the following: "Another version of this product is already installed. Installation of this version cannot continue. To configure or remove the existing version of this product, use Add/Remove Programs on the Control Panel." The Product Code is the same and it is only the version numbers that changed. I have tested the other way around without minor upgrade properties and I will correctly get this message, but why is the downgrade detection not working? We have created a few WiX packages and they all seem to be doing the same thing. So how do I get it to correctly detect a downgrade so that the correct error message appears?? Thanks for any help on this issue. -- View this message in context: http://windows-installer-xml-wix-toolset.687559.n2.nabble.com/Prevent-Downgrade-detection-not-working-tp7586426.html Sent from the wix-users mailing list archive at Nabble.com. ------------------------------------------------------------------------------ How ServiceNow helps IT people transform IT departments: 1.
