Hi lorimanepenthe,
Do you have iTunes Installed in your computer?
If not then I would recommend you to Install it first. The iTunes Setup.exe file, can be downloaded from the Apple Web site. The link is:

if iTunes is installed then use the below link to setup iTunes as the default player on your system.

Hope this information was helpful.
Let me know if this worked.
All the best!
Thanks and Regards,
