Hello Dima,
Well now your in a sticky.
16.0.1 went out of service on the 20th, and the binaries were removed.
So now you have 2 choices, you can upgrade Enforce and then uninstall / reinstall all of your detection servers, or you can open a support case and request we provide you the files.
You will first need MP1, and then need hotfix 16.0.1011.60591 (Upgraded DLP issues after 16.0 RU1 is uninstalled)
If you open a support case and request those binaries, stating you need them in order to upgrade to a supported version, we will track them down and deliver them to you.
Kind regards
Tye Snyder
