I have bought NWC 1.75 some time ago. Last year I could upgrade free to a more recent version, I don't remember the number. But I had to reinstall my computer and now I've lost this upgrade. How can I retrieve it?
I don't think it was ever possible to upgrade from version 1.75 to version 2.x for free.
Maybe you upgraded version 1.75b or 1.75c?
If you have a license for version 2.0 you can for free upgrade to version 2.1 (and hopefully also to 2.5 in the future).
The Viewer is free.
thanks Bart, in fact I had the upgrade to 1.75c. Since I bought the upgrade to 2.1, it's OK. Bye!
