State tool installation fails on Windows because running scripts is disabled on this sytem

Your state tool installation might fail with a message like this if your system is configured not to run powershell scripts downloaded from the internet.

File C:\Users\martin\Projects\cli\installers\install.ps1 cannot be loaded because running scripts is
disabled on this system. For more information, see about_Execution_Policies at
At line:1 char:1
+ .\install.ps1

    + CategoryInfo          : SecurityError: (:) [], ParentContainsErrorRecordException

You can circumvent this problem by temporarily allowing powershell scripts in your powershell session:

Set-ExecutionPolicy Unrestricted -Scope Process

Close the powershell session after you are done, or revert the change by

Set-ExecutionPolicy Undefined -Scope Process
