Horizon Setup V2 5 10 0 Execution

Look for the setup wherever you saved it and you’re going to want to right click on it then select properties. After you’ve done that look around for a button saying “Unblock”. Press this then press “Okay” or “Apply”. Make sure you’ve uninstalled Horizon then click on the setup and it should install fine.

After finding a killer PowerShell script on the interwebs, you download it and then the excitement dies when you get a lovely PSSecurityException error like the example below: File C: Scripts Script.ps1 cannot be loaded. The file C: Scripts Script.ps1 is not digitally signed. You cannot run this script on the current system.

For more information about running scripts and setting execution policy, see about_Execution_Policies at. At line:1 char:1 +. Script.ps1 + ~~~~~~~~~~~~ + CategoryInfo: SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId: UnauthorizedAccess This seems a bit strange, as when you check the PowerShell script execution policy it is set to RemoteSigned.

The big yellow arrow indicates the current status: This file is local on the disk, so it should be allowed to run, no? Remote Origins Windows knows that the script file was downloaded from the Internet. Looking at the file properties we can see that Windows has blocked access to the file to protect from potentially malicious attacks. We can click the Unblock button in the file’s property sheet to remove the restriction and allow the script to be executed. Of course we only download files that we trust from the Internet from reputable sources, right?

Every organisation will have different policies and procedures for ensuring that downloaded content is safe. Please follow your organisation’s policy for these matters. This behaviour is expected. In the actual original error message the takes us to the about_Execution_Policies content on TechNet. It says the following about RemoteSigned: Scripts can run. This is the default execution policy in Windows Server 2012 R2. Genghis khan rise to power.

- Requires a digital signature from a trusted publisher on scripts and configuration files that are downloaded from the Internet (including e-mail and instant messaging programs). TechNet covers that RemoteSigned is the default PowerShell execution policy for Windows Server 2012 R2, and Restricted is the default execution policy in Windows 8, Windows Server 2012, and Windows 8.1.

Installing Exchange automatically changes the PowerShell execution policy as Exchange makes heavy use of PowerShell scripts. Cheers, Rhoderick.
