I installed a SW license manager with the latest version available (2017 SP2).  However, I tried to activate our licenses for 2016 SP5 clients, but the manager is unable to activate.  Whenever I try, an error is reported that our SN is not entitled for a 2017 product.  However, I'd like to activate a 2016 product.  Is this possible or do I need to find an installation for an older LM version?
