The only drawback is that I don't own the right to use the software once my subscription runs out. If I were a new user it would take something like three years of subscription to make up for the purchase price of the program. Provided you have a reliable internet connection (because the license validation relies on your internet connection). Personally, I feel the Subscription model and costs are really pretty good.

And, they are now only paying a yearly maintenance fee to provide for upgrades and access to technical support. This is because the owner paid a large up front cost to purchase the right to use the software. The maintenance costs of the perpetual licenses are significantly less per year than the subscription costs.

However, people who own a perpetual version of the software and continue to pay their yearly maintenance fees will continue to get upgrades to the newer versions using their traditional license protection (Sentinel network licensing or hardware keys or such). But, once your lease runs out you lose all ability to use the software unless you renew your subscription. Meaning that if you contact them about getting a new copy of their software (or updating from an old version) they will offer to "lease" the right to use the software on a yearly basis (i.e. RISA / Nemetschek is currently only selling their subscription licensing. As such, I thought it would be a good idea to state the current policy as I understand it and offer some generic advice to those who are wondering the same thing. As a prominent former RISA employee, a number of people have approached me privately with some questions/ concerns regarding RISA's recent move towards subscription licensing.
