"Unable to Open File..." Messages in Network Installations
Description

If Symphony Math is installed in a shared computing (nComputing) or networked environment, multiple students can use the program at one time. In order for this type of use, the Symphony Learning folder and all enclosed files must be set to 'Read Only'. These settings are applied during initial installation, but may be altered if personnel make changes or a problem is encountered during an Automatic Update to the program.

When this problem occurs, the following message will be displayed when more than one student tries to use Symphony Math:

    "Unable to open file {name} because it is already open with write permission by another user."
Solution
  1. Find the 'Symphony Learning' folder on the host machine or school file server.
  2. Right-click the 'Symphony Learning folder and select 'Properties'.
  3. From the Properties dialog box, make sure the 'Read-only' checkbox is checked, and press the OK button.
      IMPORTANT: You may need to check this button two times to ensure that a check mark appears.
  4. If prompted, choose to make the changes for all subfolders and files.
