No uninstall on Wix major upgrade

Here's my code:

<?xml version="1.0" encoding="UTF-8"?>
<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
  <?define ProductName = "MyApp"?>
  <?define ProductCode = "GUID_NO1"?>
  <?define UpgradeCode = "GUID_NO2"?>
  <?define ProductVersion = "1.0.0"?>

  <Product Id="$(var.ProductCode)"
           Name="$(var.ProductName)"
           Language="1033" 
           Version="$(var.ProductVersion)"
           Manufacturer="Me"
           UpgradeCode="$(var.UpgradeCode)">

    <Package Description="My desc" 
             InstallerVersion="300"
             Compressed="yes"
             InstallScope="perMachine" />

<MajorUpgrade DowngradeErrorMessage="A newer version is already installed." />
    ...

I build, install and all goes fine. So I replace

  <?define ProductCode = "GUID_NO3"?>
  <?define UpgradeCode = "GUID_NO4"?>
  <?define ProductVersion = "1.0.1"?>

I build, install and in programs/features i found 2 MyApp, one in version 1.0.0 and one in verison 1.0.1. Of course I need the 1.0.0 to be removed.

Keeping the same guid for ProductCode will not work.

I'm using Wix 3.8.

Make sure that the UpgradeCode remains the same and change the Id to *.

<Product Id="*" Name="Stub" Language="1033" Version="$(var.Version)" 
    Manufacturer="" UpgradeCode="FAFD7276-68F3-43AF-BEBF-8F175499A243">
