Perceptive Content   Client and WebNow

Microsoft Windows 7, 8.1, and 10

Note Windows 10 is only supported on Perceptive Content 7.1.3 and above. As of December 19, 2016 Imagine deploys Perceptive Content 7.1.5

Java. Supported version: Oracle JRE version 1.8.0_144

However, there might be some rare cases where a newer version of JRE 1.8.x is found to be incompatible and must be replaced.

This means the tested java version for Imagenow version 7.1.x is Oracle JRE version 1.8.0_144

2018-11-27 Update:

  • We are asking all WebNow users to stay with Java version 1.8 and not to upgrade to a more recent version. This is because Oracle Java SE 8 is the most current supported version of Oracle Java SE that supports Java applets, and as of Oracle Java SE 11 and all future versions of Oracle Java SE, support for the Java Web Plugin (applets) has been removed. Please note that with our next upgrade (planned for mid-2019), WebNow will be retired and replaced by Perceptive Experience.  For any questions please submit a ticket to the Imagine team mailto:imaginehelp@lists.berkeley.eduThank you for your understanding.

Browser versions that are updated after users install WebNow are also assumed to work unless otherwise noted.
