Using Biamp Canvas with multiple Windows user accounts

This article explains how to set up Biamp Canvas with multiple Windows user accounts.

In some installations, a single public computer is available for all users while it’s also necessary that the same computer be used to control the sound system using Biamp Canvas. Since all Auto-Connect settings are stored in the registry for the current user, having multiple accounts would require programming these setting for all accounts which could be a daunting task. This note explains how to create a small batch file that would modify the registry when the user logs in allowing Biamp Canvas to Auto-Connect.


This procedure requires accessing the registry of your computer.  Changing entries in the Windows registry can be dangerous and can cause major problems.  Please follow these steps closely, and only perform them if you are comfortable/familiar with accessing the Windows registry.

  1. Setup Auto-Connect and make certain it works as desired, then close Biamp Canvas.
  2. Open the Registry Editor by clicking Start > Run and typing regedit
  3. On the navigation pane, expand the “HKEY_CURRENT_USER” folder.
  4. Locate the “Software” folder and expand it.
  5. Locate the “Biamp Systems” folder and expand it.
  6. Right-click on the “BiampCanvasx.x.x” folder and click “Export”. (Note: x.x.x represents the version installed)
  7. Save this file as “BiampCanvas.reg” in the local drive (C:).
  8. Close the Registry Editor.
  9. Open the Notepad (normally under Start > All Programs > Accessories).
  10. Type regedit /s followed by the location of the registry in the local drive (i.e. regedit /s C:\BiampCanvas.reg )
  11. Save this file as “BiampCanvas.bat” in the local drive (C:).
  12. Close the Notepad.
  13. Locate the BiampCanvas.bat file in the local drive and create a shortcut.
  14. Add this shortcut to “C:\Documents and settings\All Users\Start Menu\Programs\Startup”.
  15. Right click on the shortcut and click properties.
  16. Go to the advanced menu and select “Run with different credentials”.
  17. Have the administrator allow this to run with administrator privileges and click “OK”.
  18. Log out of Windows.  When you log back in as any user, Biamp Canvas will be set up to Auto Connect.


Using a Device List

If you are using Biamp Canvas to connect to Tesira devices on different subnets, then you have most likely added them to the Device List through the Tools->Options->Network window. Please refer to the Tesira Device Discover Methods article for more details on this feature. If in use, you will need to copy the XML file that contains this list into each user's directory or create a batch file to automatically perform this action.

The file is located at C:\Users\{username}\AppData\Roaming\Biamp Systems\TesiraService\200.1\ApplicationSettings.xml
