Hello,
as a customer you can download all versions that you have licensed from our download center. For evaluation purposes we provided always (and only) the latest version, which is 9.30 at the moment.
If you are customer using 9.20 and you want to evaluate the Android environment (by using the same version) - please contact us via support@embedded-wizard.de then we can provide this version directly to you.
Best regards,
Manfred.
