Windows blocks the execution of remote signed PowerShell scripts by default. If your execution policy still has this setting, you might see this error message:
C:\Users\test-user\Downloads\Install.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 https:/go.microsoft.com/fwlink/?LinkID=135170. At line:1 char:1 + .\Install.ps1 + ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + CategoryInfo : SecurityError: (:) [], PSSecurityException + FullyQualifiedErrorId : UnauthorizedAccess
Just run the following command as Administrator within a PowerShell console:
