MacBook (2012) to PC (Windows 10)


I have an MacBook dated mid 2012 and I cannot install the latest version of TeamViewer, therefore I am using an old version of TeamViewer. I am trying to connect to a PC with a NEW version of TeamViewer. The system told me that I have got an old version on my Mac and tell me to install a new version of TeamViewer (...knowing that it is not possible!). So, is there a solution to this problem? Thanks
