Wix installer error: Another version of this product is already installed. Installation of this version cannot continue

I have a wix install project converted from a msi project:

Here is the code from the Product.wxs:

Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
    <Product Id="{B058DA50-08DD-442F-BAE6-70229A1C777E}" Codepage="1252" Language="1033" Manufacturer="XXX" Name="APP" UpgradeCode="{A260D180-A94B-4E81-A79B-F87EE85C054C}" Version="2.1.4">
        <Package Compressed="yes" InstallerVersion="200" Languages="1033" Manufacturer="XXX" Platform="x64" />

 <Upgrade Id="{A260D180-A94B-4E81-A79B-F87EE85C054C}">
            <UpgradeVersion Maximum="2.1.4" Property="PREVIOUSVERSIONSINSTALLED" />
            <UpgradeVersion Minimum="2.1.4" Property="NEWERPRODUCTFOUND" OnlyDetect="yes" IncludeMinimum="yes" />
        </Upgrade>

I update the version number to 2.1.4 to 2.1.5 in the Product.wxs, rebuild the installer and run the installer on a machine already installed the 2.1.4, get a error below:

How should I resolve this error?

Solution

Looks like you want major upgrades. The ProductCode has to change every build so set it to * to get the compiler to do that for you. Also your version number much change in one of the first few versions.

MSI Defines ProductVersion as:

0-255.0-255.0-65535 rest ignored

so 1.0.1 -> 1.0.2 good. 1.0.1.2 -> 1.0.1.2 bad. You'll get duplicate entries in Add/Remove Programs.
