This 'Table is read only' error always indicates a lack of user rights. Every Reporter user-workstation needs to have full read and write access to the shared data folder and the local Reporter\Program folder. To install, you need full read and write permissions on their C drive also.
The data folder is typically located on a local server using Windows file sharing with the Volunteer Reporter software installed on each workstation. All Reporter users must have full read and write access to the data folder.
You don't have full access can be a misleading error message.
One user got this when in fact the user had no mapping to the drive in the file path.
