No License Key? No Problem!
[April 7,2012] We've heard a few questions from many of our users about the new 7-day grace period offered with our latest NumXL release. Simply put, you can now run a full version of NumXL immediately for seven days, no license key required.
Don't worry about entering a subscription key; all you need to do is open Excel and start using the Pro/Full mode of NumXL. Like what you see? After seven days you can keep working in Full mode by starting a free 30-day trial, or by downloading an annual or perpetual license key if you're full on board.
Also, be sure to check out the NumXL release notes for more details on the newest features.
