I believe we started experiencing the same issues.
Currently we are using Autodesk 2024 products, and the version of Autodesk Access I have installed is: 2.6.0.118
Autodesk Access says I have no updates available. However, as an example, my currenty installed version of Inventor is 2024.3. I know there are newer versions available.
Additionally, I just had to do an Inventor install for one of our existing users that got a new computer. Autodesk Access was automatically installed, but it seems to have been an older version that didn't call for any updates. I manually reinstalled Access (by Googling it and finding it on Autodesk's website), and the new version then called for updates.
So I guess I have two questions:
1 - Is there a certain version of Autodesk Access that stopped updating itself?
2 - If so, how does one know what version they should be running?
