Issue:
When attempting to install any AutoCAD-based software you get the following error:
Error 20 at 1 -2% when installing AutoCAD based 2022 software.
Causes:
This is usually caused by a DirectX component failing to install or Update.
To confirm this is the issue, inspect the Install.log (from here: %localappdata%\Autodesk\ODIS) you see this in the log:
Line xxx: 2021-12-06T11:06:40.643 [Install Manager: 6760, single] [InstallManager INFO] [ InstallManager::HandleInstallFailure ] Failed to install Package (upi2: {C9D7C6BF-A352-3EE7-AF06-BFE6D5507BED} name: Microsoft DirectX for Windows ) Error Code: -20 Exit Status: 2
Solution:
First, manually installed DirectX from the Microsoft Website:
https://www.microsoft.com/en-us/download/details.aspx?id=35
Then In this folder (you must have the full download package to do this step):
C:\Autodesk\Autodesk_<product name>_2022_English_Win_64bit_dlm\x64\acad
There is a pkg.acad.xml
Make a copy of that file, and rename it to pkg.acad Copy.xml.old
Then open pkg.acad.xml using Notepad and remove this line entirely (should be near the bottom):
<Package installAs="core" name="Microsoft DirectX for Windows" external="true" path="3rdParty/DirectX/pkg.dxsetup.xml" upi2="{C9D7C6BF-A352-3EE7-AF06-BFE6D5507BED}" upgradeCode="{E4625438-EBA5-36E6-A3EE-AF5DEB6E7AC0}"/>
Then save and close the pkg.acad.xml, and re-run the setup to install the software
