Hello @IgorR1 Parallels offers a trial version only for the latest version of Parallels Desktop. Here is how you can get a trial version of Parallels Desktop 11 for Mac. To get Parallels Desktop 9 for Mac, please contact our resellers like Amazon, BestBuy etc to find out if they still offer it.
The trial version is offered only for versions that are being sold now on our website. Since the release of Parallels Desktop 11, we no longer sell previous versions of Parallels Desktop. This means that the trial version is only available for Parallels Desktop 11. You could still purchase a previous version of Parallels Desktop from any of your local re-sellers.
