Important Notes

Content
Updated Content for Revit 2021.1 is not included in the patch deliverable and is provided on the Autodesk Knowledge Network, link.
Update installation may fail if the original Content path location is not accessible.

Install
After applying the hotfix, Generative Design command may cause a “RestDynamoCore.exe – This application could not be started” errors. A reboot of the system should resolve the errors.
In some scenarios the original RVT.msi may be required to install the hotfix. If you are prompted for to specify the RVT.msi version and do not have access to the original installation files you may download the RVT.msi as follows. There are several unique Revit 2021 full product installers which have been released and each includes a unique version of the RVT.msi file. The following is the simplest way to identify which full product installer was used to install Revit 2021 on a workstation:
1. Open the Windows Registry Editor.
2. Browse to and select the HKEY_LOCAL_MACHINESOFTWAREAutodeskUPI2{7346B4A0-2100-0510-0000-705C0D862004} registry key in the left column.
3. In the right column, make note of the BuildNumber value.

If the BuildNumber is 21.0.0.383, then the installation used the initial Revit 2021 full product installer and the required RVT.msi is available here: link

If the BuildNumber is 21.1.1.109, then the installation used the Revit 2021.1 full product installer and the required RVT.msi is available here: link

If the BuildNumber is 21.1.11.27, then the installation used the Revit 2021.1.1 full product installer and the required RVT.msi is available here: link

Uninstall
Revit 2021 updates can be uninstalled to revert Autodesk Revit 2021 to its pre-update state.
Uninstalling this update after being applied to a Revit 2021.1 installation may require the original installation media to complete without error.
Uninstalling this update after being applied to a Revit 2021.1 installation may cause the Revit version displayed in Windows>Add/Remove Programs to be blank.

Revit 2020.2.4

Software embedded in the update executable:

Revit 2020 – version 20.2.40.65
