This copies an encoded offline activation url to your clipboard, which you just have to decode to get the missing Challenge Code. Spectrasonics now wants you to request a challenge code online but an offline activation is still possible, just a bit hidden at the bottom of the authorization page by clicking the small blue 'click here'. That took a bit of research but wasn't very complicated in the end. Therefore I applied the patches manually (also to the new Trilian Update, where no previous RSA2048 patch was available).
Omnisphere 2.6.4c | Keyscape 1.2.0c | Trilian 1.5.0d | November 25th 2020 Info: These are the most recent updates for Spectrasonics Omnisphere 2.6.4c, Keyscape 1.2.0c & Trilian 1.5.0d including Patched files for Mac & Windows Notes: Since Spectrasonics changed their Authorization method a bit, it's not possible anymore to patch the plugins using R2R's keygen.
