If you are asking if it's possible to simply plug in an ID and Poof, you are upgraded, the answer is no. You will typically have to uninstall whatever version (9 in your case) and install the new version.
As with any software, newer releases bring better capabilities and overall improvements. Whether an upgrade is "worth it" is entirely dependent on how well your existing version is working for you and whether you see the enhancements as being useful. But that's generally speaking for any software. With RoboHelp, it's a bit different. Browsers are constantly evolving and RoboHelp evolves with them. So it's a good idea to always stay on top of upgrades with a tool like RoboHelp so you can ensure the outputs you create will continue to work as browsers evolve.
Sorry, but I don't understand yet.
I have to uninstall the current version and install whatever version (that's OK for me). My question is: do we have to purchase a new license key again? Can't we just use our same license in the newer version?
I'm not sure exactly where the confusion is. But when I read your first post, it seems you have RoboHelp 9. You want to upgrade it to a different version. Perhaps 10 or 11 or even 2015 Release. Each "key" is tied to the specific version. So if you have a key for version 9 and you want to upgrade to any newer version, you likely need to acquire (by purchasing) a new key.
The only confusion with that would be in the event you are using one of the newer "subscription" models Adobe offers. And I'm not sure they offer that yet for RoboHelp or TCS. I'm not sure how the licensing with keys and whatnot work for that type of setup.
Maybe someone else knows and will pop in to advise.
There is now a subscription option but I don't believe it was an option
with Rh 9 so a new key will be needed, either for a perpetual licence or a
The latter is a good option if upgrading regularly but maybe that's not the
Thank you all.
