Check permissions for the Windows system temp folder (usually %SystemRoot%\TEMP).
- Make sure CREATOR OWNER has full control for 'Subfolders and files only'
- Make sure local 'Users' group has 'Traverse Folder', 'Create Files', and 'Create Folders' permissions for 'This folder and subfolders'.
- Make sure inheritable permissions from the parent are not allowed. This is important because unwanted allow and deny rules may be inherited from parent.
