Today Avid announced that the deadline to upgrade to Sibelius 8 from Sibelius 7.5 or earlier at an introductory price is being extended to July 6, 2016, “due to the unprecedented and overwhelming popularity of this upgrade offer over the past two weeks,” according to an updated post on the official Avid blog.
Previously, Avid set the deadline for today, June 30.
Activation problems may have also played a role in the decision. A number of users on a monthly or annual subscription have reported problems when updating to Sibelius 8.4. Sibelius support representative Vee Jimenez has recommended that users experiencing this issue “uninstall 8.4 and revert to 8.3 until we have an 8.4.1 fix available, which will handle the license correctly.”
UPDATE: 4:00 pm — Sibelius 8.4.1 is now available. Product designer Joe Pearson said: “It contains a single fix for an issue that could prevent subscription users from running Sibelius. If you’re already successfully running 8.4.0 there is no need to update.”
