How to upgrade Dune from 3.2 to 3.4

[khr128]

I have purchased Dune 3 some time ago, and I have the license key.
How do I upgrade to the latest version. I tried to install demo version, but now I don't know where to type in my license key.

Thanks for your help.

Then do this:
- enter login credentials [username + password]
- "Access user service area"
- "Access downloads area"
- find DUNE 3 in the list
- "Show files"
- where it says Latest version: 3.41, click on "Download"

From there, find it on your computer, unpack the installer, run it and finish through the setup process.
