The BSOD STOP message is "VMMRO.RO Address B576F7CB base at B572B000. Nevertheless, after uninstalling, rebooting, reinstalling fresh and rebooting, the same problem continues with the Host Only Adapter. In fact, on my final installation the Host Only Adapter was not created and I received an error when attempting to create one manually in the VB properties. So I've uninstalled 3.2.2 rebooted and downgraded to 3.2.0 and everything is working properly. So whatever changed in 3.2.2 isn't working on my system. As it stands, I'm staying with 3.2.0 for now.
