Solution:

Since Version 2014 Autodesk provides uninstall scripts within the Admin Image Folder.

Open the ImageName_Uninstall.txt with a Notepad and remove the comments by deleting the "::" characters at the beginning of the "::call :funcUninstall" command line for each product that you want to uninstall. Save the file as a batch file and execute with at least admin privileges.

For Example, to remove Autodesk Material Library Base Resolution Image Library 2018 :: has been removed in front to uncomment:

::========================================================================================
::Uncomment (by removing the ::) the command lines below to uninstall products
::========================================================================================

::::== Autodesk Material Library 2018
::call :funcUninstall {7847611E-92E9-4917-B395-71C91D523104}, "Autodesk Material Library 2018"
