  <!-- Product/@Id is auto-generated so every Bazel version (including release
       candidates) has a unique product GUID. This is fine, all upgrades are
       "Major upgrades" (see
       https://www.firegiant.com/wix/tutorial/upgrades-and-modularization/).

       IMPORTANT: to see the Product GUID of an .msi file:
         1. install the Windows SDK
         2. find the Orca installer underneath (Orca-x86_en-us.msi) and run it
         3. open the .msi file with Orca
         4. open the "Property" table: the "ProductCode" property is the
            generated Product/@Id GUID
  -->

  <!-- IMPORTANT: Product/@UpgradeCode must be the same for backwards-compatible
       versions, but a new code is needed when an incompatible release comes.

       Versions with the same UpgradeCode are upgraded: higher versions replace
       lower versions (e.g. version 1.5.2 replaces version 1.0.3). Downgrading
       is not permitted.
       Versions with different UpgradeCodes can co-exist (e.g version 2.0.4rc5
       can co-exist with version 1.2.0).
