Unable to display graphics from an I/A Series R2 Enterprise Server or UNC.

Issue

An Internet Explorer ActiveX function involving the running of Java applets used to display the I/A Series R2 graphics prevents the Java applet from executing properly.

Environment

I/A Series R2 software release 522.v2, 529 or 532

Cause

Microsoft changed the procedure by which Internet Explorer handles third party ActiveX applets, including the Java applets used in the I/A Series R2 system.  This change was applied as an update to all older versions of Internet Explorer and is included in Internet Explorer 8.

Resolution

There was a workaround provided with the R2 522.v2 release that can be used to prevent this Java applet activation issue from happening.
The update consists of adding or modifying some of the information in the station.properties files and applies to both ES based stations and UNC based stations.

1. To update the Enterprise Server / WorkPlace Pro, save and backup the station database accordingly.
While in the admin tool, open the station.properties file.  Select menu item Admin Tool -> Host -> Edit File -> System Properties.  Edit the file by adding the following text to the end of the file.   Make sure not to delete the # character as this specifies a comment line.  Save and close the system.properties file (File ->Save).

# This is used to disable the IE ActiveX activation fix. If set to
# to false, then the user will be required to click on the applet
# before he is able to interact with it (only effects IE users).
ie.activex.activation=false

2. To update the UNCs, log into the UNC using the Admin Tool and open the station.properties file.  Select menu item Admin Tool -> Host -> Edit File -> System Properties.  Edit the file by adding the following text to the end of the file. Make sure not to delete the # character as this specifies a comment line.  Save and close the system.properties file (File -> Save).

# This is used to disable the IE ActiveX activation fix. If set to
# to false, then the user will be required to click on the applet
# before he is able to interact with it (only effects IE users).
ie.activex.activation=false
