When modifying the Shared Directory Configuration and specifying a folder for the Common tool settings section, you may see the following messages in the status section:
Could not copy file: notesDtApp.chm, Reason: 20
Could not copy file: NotesDtApp.exe, Reason: 20
Could not copy file: Notesdtapp.ini, Reason: 20
Could not copy file: _notesdtapp.exe, Reason: 20
This is caused because the ToolsCache folder is selected for the location of the Common tools setting folder.
To resolve this issue, select a different folder than the ToolsCache folder. The selected folder can be a newly created blank folder or share.
