How do I make V7 my default version?

It seems that eventhough I have installed V7, V6 seems to be the default version.
How can I change this?

Cheers

Do you mean by this that when you select a .3dm file in Windows Explorer it starts with V6? This is a “file association” in Explorer. Use Explorer to find a .3dm file and right click on it. The menu that pops up will have an item labelled “Open with”. Click that and then click “Rhinocerous 7” if it appears, otherwise click “Choose another app”. The second approach has a checkbox for “Always use this app to open .3dm files”. I can’t remember whether the first choice automatically sets the “Always use” option or whether it’s a one-time thing.

Thanks!!
