if statement comparing path with a space AutoHotKey

Because of the space in the space I get this error :

Error: The following variable name contains an illegal character C:\Users\Ko La\Desktop

How can I resolve this?

if (%A_ScriptDir%="C:\Users\Ko La\Desktop")
return
else{
MsgBox, 4, , Do you want to rename the files in %A_ScriptDir%? (Press YES or NO)
IfMsgBox No
    return
else{
    MsgBox Rename is done
    return
}
}

I also get the same error with when I use the short name :

if (%A_ScriptDir%="C:\Users\KOLA~1\Desktop")
