The option to accept/decline our installer, though, is up to Sonivox, not us. That should prevent a lot of the catastrophic conflicts that you are worried about.

Our installers (even ones included in other installers such as Sonivox) are smart enough to handle versioning, and will not overwrite newer files with older ones. The version of ILok it installs is over 5 years old (!!!)and has severe issues with a recent build Windows 10. This is likely to be affecting/will affect other uses and requires immediate action by Sonivox (who I contacted) and by iLok (who I can't yet find contact details for). I reproduced the bug exactly by repeating the same steps. I already have the latest version of iLok License Manager installed and it works fine with everything else. The problem can only be recovered by wiping the drive and reinstalling Windows completely or restoring from a recovery image. I suspect this somehow catastrophically conflicts with the latest version of iLok License Manager and caused an unrecoverable boot failure with the stopcode error: 'page fault in a nonpaged area' with tpkd.sys failing. There was no option to accept/decline this extra install. I already had iLok License Manager installed but the installer for VocalizerPro installed what appeared to be iLok again. I downloaded Sonivox VocalizerPro 1.3 on the Plugin Boutique site. Watch out if you have iLok Licence Manager installed and then install Sonivox software that installs iLok inside its own installer.
