TLS 1.2

Tony Coffman -

TLS 1.2 Support 

With the release of v7.3, on May 31st 2018, VDM will support TLS 1.2 (Transport Layer Security) for our client subscription and licensing processes, the download and update managers as well as our Web Reports service.  TLS is the successor of SSL and many organizations are implementing client and server protocol policies that require all systems communicate over a minimum of TLS 1.2.

If you receive an error similar to the following while registering or launching VDM;

Error During Registration: The underlying connection was closed: Could not establish trust relationship for the SSL/TLS secure channel

it is likely your network administrator is enforcing the TLS 1.2 protocol.  To resolve this challenge, please update to the latest version of VDM.  If you are unable to run the standard update process, located under the help menu, you will be required to manually update your installation of VDM.  For more information on the manual update process, please review this article: Manual Update Process.

.Net Framework Requirement
To support TLS 1.2, VDM's minimum .Net Framework requirement has been increased from 4.5 to 4.6.2.  You can find the .Net Framework download for 4.6.2 here

While we've formally discontinued support for Windows XP several years ago, VDM still functioned nominally up to v7.2.1.1.  Please note that Windows XP does not support .Net 4.6.2.  If you are running Windows XP, you cannot update VDM beyond v7.2.1.1.

Web Reports Requirement
Web Reports has an additional Microsoft SQL Server minimum version requirement to support TLS 1.2; Microsoft SQL Server 2014 SP1 CU5 and has been tested and approved to run on Microsoft SQL Server 2014 SP2 CU11 and later.  To access the latest SQL Server build versions, please click here.

Older TLS Protocols
BridgeWorks will continue to support TLS 1.0 and 1.1 for clients that remain on older versions of VDM and the legacy protocols through 2018.  We will discontinue for TLS 1.0 and 1.1 by December 31, 2019.
