Autodesk® recently announced a security vulnerability for current single-user subscribers using 2014 - 2017 versions of certain products, as well as current release versions of some products that have cloud-connected features (such as Revit®.) A full list of products and year releases affected, as well as more information from Autodesk can be found here: Transport Layer Security (TLS): Updates Required to Maintain Software Access
 
NOTE: Customers using products or year releases NOT listed at the link above, and customers using perpetual licenses OR multi-user subscription licenses will NOT be affected by this issue.
 
The Issue
Autodesk identified a vulnerability to man-in-the-middle (MITM) attacks in Transport Layer Security (TLS) 1.0/1.1 that can compromise data exchanges. Because of this issue, Autodesk Identity Services will begin using Transport Layer Security (TLS) 1.2, effective August 3, 2019. After that time, Autodesk Identity Services will no longer support TLS 1.0 and TLS 1.1, resulting in connectivity issues if action is not taken prior to August 3, 2019.
 
What Should You Do?
To avoid connectivity issues on or after August 3, 2019, you will need to do one of two things: 

1. Download and install a newer release version of your software through your Autodesk Account or the Autodesk Virtual Agent (AVA) before August 3, 2019.
2. Download the appropriate License & Identity patch before August 3, 2019. Downloads can be found by clicking the appropriate year release next to the product you're using at this link: Transport Layer Security (TLS): Updates Required to Maintain Software Access​

​We suggest taking a look at the wider variety of materials available in the Autodesk® Material Library. If you like those materials, it is possible to set the Autodesk® Material Library as the active Material and/or Appearance Library in any Autodesk® Inventor® Project.
 
It is also possible to copy those materials to your Inventor® Material Library, or a custom Library, specific to your company’s standards.
