Even though there were improvements in the 1607 and the 1703 releases with setup.exe command lines to support more third-party encryption systems, you can still end up in a situation where an in-place upgrade is not possible or runs into a severe error. To prevent this problem, you need to upgrade to the newest version of your product. If this still does not help, you can only decrypt your drive (which is time consuming) or use a classic wipe and load without retaining your apps, data, and settings.
