WiX 3.14.0.6526 Development build

This is the last development build that was published in the WiX website ( https://wixtoolset.org/docs/v3/releases/v3-14-0-6526/ ) at the time of creating this fork. The links are dead now, though.
The builds were used on one of the CIs we run, so we're using this as a mirror until we upgrade to WiX 4.
Not to use in production.
