I have both PowerShell 5.1 and PowerShell 7.0 on my computer. How can I enforce a mandatory version (a specific version, not a minimum or maximum version #) of PowerShell for a given script (in this case, PowerShell 7.0)?

another option is to use #Requires statement
#Requires -Version 7.0 here is the reference from Microsoft support

-1. This will stipulate the minimum version needed to run the script, but it will not force a certain version of PowerShell, as the question requires.
If it's a script being invoked in a PS shell, you could relaunch it if it's not the correct version.
# At beginning of .ps1 if ($PSVersionTable.PSVersion -ne [Version]"5.1") { # Re-launch as version 5 if we're not already powershell -Version 5.1 -File $MyInvocation.MyCommand.Definition exit } # Your script code If the scripts are launched via Task Scheduler, you could just use the full path to the .exe in the "Actions -> Start a program" section, as they have separate install locations.
Requiresdirective can prevent running the script in a lower PS version.
