## Steps

1. If the policy installation ends with an error, read the messages both in the main window and in the Issues tab and correct as necessary. Warnings do not prevent policy installation; you can still press Continue in the policy installation even if a warning is triggered. You can also validate the policy separately to see if there are issues that prevent you from installing it.
2. Try installing the policy with the Keep Previous Configuration Definitions option deselected. Normally, the option should be selected. Under certain conditions, the old configuration definitions might not be compatible with the new policy, so the engine cannot fulfill this request and policy installation fails.
   CAUTION:
   When the policy is installed with the Keep Previous Configuration Definitions option deselected, even some currently active connections that are allowed in the new policy can be cut. The applications must then reopen the connections.
3. Make sure that a current dynamic update package is imported and activated on the Management Server.
