Presentation Standalone problem

Hello everybody.
Latelly I mostly use Animate to create interactive presentations. My clients sometimes have problems with the exe file because of flash player version I use (most of the times have to export as FP 26 to work). The last one I made says, when opening, that the player is too old and to update it (wich ofcourse is impossible to do). Is this happening to someone else? Is there a way to fix this? Are my days in creating presentations with Animate almost done? 😞 🙂
Thank you!
