Installing a new Canopy version

Canopy will not notify you when updates are available. You can check this article for a new Canopy version, or check the current version directly on the Canopy download page

Canopy 2.1 supports both Python 2.7 and Python 3.5.

The current Canopy version is 2.1.3, released June 16, 2017. We recommend and request that all Canopy 2 users update to this version, which provides much more robust installation of Python environments, especially when under load from anti-virus scanners. See

Users of Canopy version 1 will need to fully uninstall Canopy and should also delete the other Canopy v1 directories, before installing Canopy version 2. See Updating from Canopy v1 to Canopy v2.

Existing users of Canopy version 2 do not need to uninstall their previous installation. This will be done by the newer installer.

 

Which Canopy installer should I download?

Your choice of installer determines your default Canopy User Python environment, but if you have an internet connection, this is not a restrictive choice, because you can subsequently create different additional environments from the Canopy Preferences dialog. See "Managing and switching between Python 2.7 and 3.5 environments".

 

Python 2.7 or Python 3.5? 

Download whichever you expect to use most frequently. (Note that the Canopy Data Import Tool and the Labview Python Toolkit are not yet available for Python 3.) As just described, this choice is not restrictive. You can update from a Canopy 2 installation that defaults to Python 2.7, to one that defaults to Python 3.5, or vice-versa. The active Canopy User Python environment will be replaced on subsequent startup only if you so request, or you can replace it later from the Tools menu => Troubleshoot => Reset Python Environment.

 

Standard or Full package set? (Subscribers only)

Most users should download the Standard installer to save disk space, time, and unnecessary package, and use the Package Manager to install any additional packages that they need. The notable exceptions would be:

  • If you are installing on an isolated / internet-disconnected system.
  • If you are a sysadmin installing for multiple users, especially with a Managed Common Install.

You can update from a Canopy 2 installation that defaults to a Standard package set to one that defaults to a Full package set, or vice-versa. The active Canopy User Python environment will be replaced on subsequent startup only if you so request, or you can replace it later from the Tools menu => Troubleshoot => Reset Python Environment.

 

64-bit or 32-bit architecture? (Windows only)

Most users should download the 64-bit installer. The notable exceptions would be:

  • If you are installing on 32-bit Windows (rare).
  • If you are installing on an isolated / internet-disconnected system and you need 32-bit Python.
  • If you are a sysadmin installing for multiple users who only need 32-bit Python.
  • To update an existing installation of 32-bit Canopy v2.

Note that in Canopy 2.1, in addition to determining your default Canopy User Python environment, this installer choice also determines the architecture of the Canopy application. Therefore
