We have completed our phased roll out of the SI5.5 upgrade. Currently all customers using SI5 are now able to upgrade to SI5.5.
To upgrade, select “Check for Server Updates” by going to Start\All Programs\D-Tools\Check for Server Updates and you will see that the SI5.5 server upgrade is available. You must upgrade the server before any desktop clients are upgraded. Please follow the upgrade instructions in this blog posting http://www.d-toolsblog.com/product-view/critical-si55-update-notice/
As with any software upgrade it is extremely important to back up your files prior to the upgrade process. Please do not skip this step.
Thanks and best regards,
