• Data files: Canvus client stores data files for your local canvases.
• License files: Canvus client requires a license file.
• Application files: Canvus client application itself.
• Screen configuration file: Canvus requires a screen.xml file which specifies how content is rendered on the operating system desktop.
• Input configuration file: Canvus requires a config.txt file which specifies how input from touchscreens is mapped on the application content.

Configuration file

The configuration file for Canvus client is called mt-canvus.ini. The Canvus client installation comes with an example configuration file that can be used as a reference.

Where is mt-canvus.ini on Windows computers?

• Working version:

  Canvus client automatically searches the following locations in order:

  1. %APPDATA%\MultiTaction\canvus\mt-canvus.ini
  2. %PROGRAMDATA%\MultiTaction\canvus\mt-canvus.ini

  Where %APPDATA% refers to the user profile of the user running Canvus client.

• Example version: C:\Program Files\MT Canvus\Examples\mt-canvus.ini

Where is mt-canvus.ini on Ubuntu computers?

• Working version:

  Canvus client automatically searches the following locations in order:

  1. ~/MultiTaction/canvus/mt-canvus.ini
  2. /etc/MultiTaction/canvus/mt-canvus.ini

  Where ~/ refers to the home folder of the user running Canvus client.

• Example version: /opt/mt-canvus-<version>/Examples/mt-canvus.ini

Where is my data?

Canvus client stores data files for local canvases in a subfolder under the root folder specified in your client configuration file. The default location depends on the operating system:

• Windows: %APPDATA%\MultiTaction\canvus-data\data-300
• Ubuntu: ~/MultiTaction/canvus-data/data-300

Where are the log files?

Canvus client logs take this file name format: log<timestamp>-<num>.log. Find these log files in the following folders:

• Windows: %LOCALAPPDATA%\MultiTaction\canvus\logs
• Ubuntu: ~/MultiTaction/canvus/logs/

Note

When Canvus client runs in single user mode, log files are not created by default.

Note

If Canvus client is started from Launcher, log entries are written to a pipeline log file. You can find pipeline log files here:

• Windows computers: %LOCALAPPDATA%\MultiTaction\launcher\logs
• Ubuntu computers: ~/MultiTaction/launcher/logs

Where is my client license?

The location for an activated Canvus client license depends on the operating system:

• Windows: Canvus client searches these folders for a license:
  • %LOCALAPPDATA%\MultiTaction\Licenses
  • %PROGRAMDATA%\MultiTaction\Licenses
  • %APPDATA%\MultiTouch\Licenses
• Ubuntu: Canvus client searches these folders for a license:
  • ~/MultiTaction/Licenses
  • /etc/MultiTaction/Licenses
  • ~/.MultiTouch/Licenses

Where is screen.xml?

The location of screen.xml (see configure-graphics-coordinates) depends on the operating system:

• Windows: Canvus client searches these locations for screen.xml in order:

  1. %APPDATA%\MultiTouch\screen.xml
  2. %PROGRAMDATA%\MultiTaction\screen.xml

  Where %APPDATA% refers to the user profile of the user running Canvus client (e.g. C:\Users\multi\AppData\Roaming).

• Ubuntu: Canvus client searches these locations for screen.xml in order:

  1. ~/.MultiTouch/screen.xml
  2. /etc/MultiTaction/screen.xml

  Where ~/ refers to the home folder of the user running Canvus client (e.g. /home/multi).

Note

If Canvus does not find a copy of screen.xml in either location, it automatically creates a default configuration in the location under current user profile.

If you want to use a system-wide configuration, just remove any screen.xml file under the user\'s profile and ensure the system-wide configuration file exists.

Where is config.txt?

The location of config.txt (see configure-input-mapping) depends on the operating system:

• Windows: Canvus client searches these locations for config.txt in order:

  1. %APPDATA%\MultiTouch\config.txt
  2. %PROGRAMDATA%\MultiTaction\config.txt

  Where %APPDATA% refers to the user profile of the user running Canvus client (e.g. C:\Users\multi\AppData\Roaming).

• Ubuntu: Canvus client searches these locations for config.txt in order:

  1. ~/.MultiTouch/config.txt
  2. /etc/MultiTaction/config.txt

  Where ~/ refers to the home folder of the user running Canvus client (e.g. /home/multi).

Note

If Canvus does not find a copy of config.txt in either location, it automatically creates a default configuration in the location under current user profile.

If you want to use a system-wide configuration, just remove any config.txt file under the user\'s profile and ensure the system-wide configuration file exists.

Where is Canvus client application binary?

The Canvus client application itself ([mt-canvus-app.exe]{.title-ref} on Windows and [mt-canvus-app]{.title-ref} on Ubuntu) can be found in the following locations:

• Windows: %PROGRAMFILES%\MT Canvus\bin
• Ubuntu: /opt/mt-canvus-<version>/bin

Tip

On Ubuntu, you can have multiple versions of Canvus client installed simultaneously. Replace <version> with the version you have installed. For example, /opt/mt-canvus-26.4.0/bin.
