quick support version incompatible

Hi,

We have 3 Teamviewers 12 commercial licence and some of our clients use a customised "get team viewer" link.

This link is very usefull to us because it deliver the right software (Windows, Mac or linux) to our client that sometime doesn't know what he is using.

But now the link point to the version 13 of the quicksupport that is not compatible with our 12 licence.

Is there a way to fix that ? (beside buying new licence)

PS : sorry for my broken english.
