On a Windows XP computer with Service Pack 2 (SP2) installed, or a Windows 2003 computer with Service Pack 1 (SP1) installed, downloading Sophos tools, including Resolve tools, may yield a security warning:

The publisher could not be verified. Are you sure you want to run this software?

The publisher is listed as 'Unknown'.

This warning appears because of the stringent default security settings for Windows XP SP2 and Windows 2003 SP1.

What to do

  1. Check that you are downloading the program from the correct web address.
  2. Ignore the message and run the program.

If you need more information or guidance, then please contact technical support.
