Please put Horizon’s setup file into the Norton AV exclusions, and allow the setup file through the firewall, as its needed and the .net framework thats needed the 3.5 default is the minimal for this software. [quote=“Chris, post:3, topic:1838, full:true”]
3.5 sp1
[/quote] Also remember to run the setup as Admin as this will allow it to run fully, as if ran on a limited account it will run into permission issues. Also please take a look at this thread to help you add the setup to your Norton Exclusions so it can run. Failed to Connect to Server or are in Offline Mode? Look here!
