Dear VYKON Partner,
Tridium has issued a software patch for a recently discovered technical issue affecting VYKON Enterprise Security Supervisors that use an MSSQL database.
When updating these VYKON Enterprise Security Supervisors to version 188.8.131.52, the update does not complete, and the MSSQL database is rendered unusable.
Please note that this issue does not affect new installations of 184.108.40.206, and VYKON Enterprise Security Supervisors installed with a MySQL database are not affected.
Should you have an affected VYKON Enterprise Security Supervisor, there are two ways to obtain the software patch. Niagara Community login will be required.
The entsec.jar file has been uploaded to the Niagara Community VYKON group here: To download the complete build with the patch included, visit https://software.niagara-central.com/ord?portal:/download/5361 for “Version 220.127.116.11 dated March 13, 2017”
