I have an new Windows 11 System and I try to install a script
under Windows Powershell ISE as follows

PS C:WindowsSystem32> 
"_CommonHintergrundLockscreen ProgrammCollect-Lockscreens11.ps1" -Install

which was fine under Windows 10

After writing in Windows (11) Powershell ISE the same command

"_CommonHintergrundLockscreen ProgrammCollect-Lockscreens11.ps1" -Install

I get the error message

In Zeile:1 Zeichen:73
+ ... nHintergrundLockscreen ProgrammCollect-Lockscreens11.ps1" -Install
+                                                                  ~~~~~~~~

unexpected Token "-Install" in expression or statement.
    + CategoryInfo          : ParserError: (:) [], ParentContainsErrorRecordException

What do I wrong? Thank you very much for helping
