When installing Redgate tools on servers not connected to the internet, the installer may fail with a verification error.

Possible cause

If the machine has been disconnected from the internet for a long time, the Windows security certificates may be out of date.

How to fix

Allowing the server to connect to the internet will let Windows update its security certificates automatically and allow Redgate tools to be installed.

If you continue to experience problems, please contact Redgate support.
