We are running Service Desk Pro version 8.0.0 build 8000. When I try to deploy through the Discovery / Agent Settings clicking on Download Agent, the installation starts asking if I want to run ManageEngineAssetExplorerAgent.msi

 

When I click run I get a security warning "Windows has found a problem with this file" "The file was blocked because it does not have a valid digital signature that verifies the publisher"

 

The installation then fails; if however I save the file, don't click Run, go into Windows Explorer and run the MSI file the software installs without problem.

 

The clients I am trying to install on are all Windows 7 Pro a mixture of 32bit and 64bit versions.
