Unable to install True Image 10

I've downloaded a trial version of True Image Home.
When i start the installation i get a security alert:
"The driver software you are installing for:
Acronis True Image Backup Archive Explorer
has not been properly signed with Authenticode(TM) ..."

After i click on "proceed installation" the installation is aborted with the following message: The installation was interrupted before Acronis True Image Home could be installed.

Can anyone telling how to solve this?
Thanx.
