Using -executionpolicy bypass -file?

Run this command at a PowerShell console, and post the results:

Get-ExecutionPolicy -List

It’s possible that execution policy is being assigned to you via Group Policy; if that’s the case, you can’t override it with the -ExecutionPolicy parameter. This is from the about_Execution_Policies help file:

EXECUTION POLICY PRECEDENCE

When determining the effective execution policy for a 
session, Windows PowerShell evaluates the execution policies
in the following precedence order:

    - Group Policy: Computer Configuration
    - Group Policy: User Configuration
    - Execution Policy: Process (or PowerShell.exe -ExecutionPolicy)
    - Execution Policy: CurrentUser
    - Execution Policy: LocalMachine
