The above error message indicates that the user who is logged in or the user account running the TIBCO Spotfire Server service does not have access to the "<spotfire server installation directory>\tomcat\" directory. To resolve, update the file/folder permissions for the user for the <spotfire server installation directory>\tomcat\" folder. Alternatively, you can also give full access to the Everyone group (at least temporarily as a diagnostic test to confirm it is folder permissions is the root cause).
If the issue still persists after validating the user permissions to the file/folders, please contact TIBCO Support at
