We have encountered an issue with X50 and B.O.D in Pro Tools on Windows where the plugin will not be validated by PT.
The reason for this is mistakenly using a digital code signing certificate with a short expiration date on Windows
If you are affected by this issue, please send us an enquiry from the website and we will send you a link for a hotfix to workaround this issue. (A second workaround is loading the VST version in a VST-wrapper).
The original installer will be updated as soon as possible, we are very sorry for the inconvenience!
Update: The a updated installer is available, just re-download the v2.4.6 windows installer
