I won't tell anyone you tried typing it instead of copying and pasting 😅</li> </ul> </li> <li>Does the user/script-running account have the correct permissions to do everything you need it to? <ul> <li>Folder permissions are a common issue</li> </ul> </li> </ul> <h2> Trust issues </h2> <ul> <li>Does the account running the script trust your signature? <ul> <li>You may need to trust/re-trust your signature, especially if you were recently issued a new code signing cert</li> </ul> </li> <li>If possible, on the machine running the task, open up a command prompt (or PowerShell!) and try launching PowerShell as the user running the task: <code>runas /user:example.edu\taskrunner powershell.exe</code> <ul> <li>Try running your script in the new PowerShell window that just popped up</li> <li>When it asks you to trust your script, you say <del>yes</del> <code>[A]lways</code>!</li> </ul> </li> </ul> <p>I hope this saves at least a few people from a few moments of frustration.
