I would make it a requirement of installation for 0.9.9 and greater
that all previous versions be uninstalled prior to installation and
not even try to do it as part of the install. Have the install test
the presence of prior drivers and have it abort it install with a
please uninstall first message.

Then all you need to to write-up a manual uninstall procedure for the
differing versions and include it as a README to the download.

It's both the easiest and safest approach.
