Unblock a Publisher

I am trying to download a few games from Shockwave.  After the files copy, it will not install.  I am recieving an error message stating "This Publisher has been blocked from running software on this machine"

I have been downloading from Shockwave for years and I have not asked that any publishers be blocked. 

How do I unblock the publisher to allow the games to run?

Thank you
