Windows Powershell doesn't seem to accept target paths with spaces
This worked for me:
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned C:\Program Files\My` Scripts\CenterCursor
Note that you will need a ` after each word (before the space) and you don't need the outer ".

In a more general case, you can use the following syntax to run any PowerShell script with space in the path:
&("C:\any path with spaces in it\")
In your case, that would be:
&("C:\Program Files\My Scripts\CenterCursor")
Edit: this only works if you are using windows powershell

You might be able to cheat by using the short name.
C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe -ExecutionPolicy RemoteSigned "C:\Progra~1\MyScri~1\CenterCursor"
I guessed your short names based on likelihood, but you can find the real ones using methods from this question like dir /x
