Deleting other files and folders

This error message indicates that a file is missing in a support part of the installation. Ironically, this can be solved by deleting more files/folders, which prevents the relevant logic from trying to find the missing file.

To do this, delete “%APPLOCALDATA%\Autodesk\webdeploy\meta\streamer”. The most notable negative effect is that you cannot execute the uninstall command for programs and functions in the Control Panel (but this will not work for the moment anyway). After the next update, which is scheduled in a few weeks, it should heal on its own and you will be fully functional again.

If you don’t want to wait, just delete the entire “%APPLOCALDATA%\Autodesk\webdeploy” folder and reinstall it from our website.
