If you have Carrara 7 pro, the last version released was 7.2 , and if you have that, ....that’s it.
If you don’t have C7.2, then you should reset your download from your Account (Itemised Order History)
and that should give you the most recent available version ...C7.2
to find out what version of Carrara you have,...
click on the little Daz triangle logo at the top left of your screen, and go to About Carrara.
That will bring up the C7 splash screen, and there should be a version number there, at the bottom right corner.
What issues are you having with running C7 in Windows 7 ?
maybe I can help !
There’s no Hidden files,.. just a new web site and Forum, which means a different route to find the same files.
Hope it helps
