Aug 8, 2019 – Autodesk released a set of Combo Security Hotfixes for multiple releases of AutoCAD and AutoCAD-based products
The Autodesk AutoCAD Combo Security Hotfixes are available via the Autodesk Desktop App or via download from the Autodesk subscription site. Each release Hotfix requires access to the original install resources.
AutoCAD Combo Security Hotfixes
Each AutoCAD Combo Security Hotfix improves the security stability and behavior of the AutoCAD based software that is updated.
Important AutoCAD Combo Security Hotfix Notes
These Combo Security Hotfixes will automatically apply all the available product Updates for all the AutoCAD-based software installed during installation.
If you want to install older product enhancements and/or add packages not yet installed, do so prior to installing these AutoCAD Combo Security Hotfixes.
These Hotfixes change the AutoCAD-based software install behavior. The installation of the 2017 AutoCAD Combo Security Hotfix will block subsequent installs of 2018 release product.
For new computer workstation builds which require support for multiple releases of an AutoCAD-based product you do NOT want to install the specific AutoCAD Combo Security Hotfix for the earlier release until all of the software and update release versions are installed.
Although not recommended, you can use the Control Panel (Programs and Features on Windows 10) to rollback this combo security Hotfix. See the Release Notes below for AutoCAD 2017 exceptions.
