# Download

Using CogNeed in “Dual Channel” mode requires installing a Windows or Linux application.

This installation requires administrator rights on your workstation. Contact your administrator if you would like to proceed with this installation.

{% hint style="info" %}
**In general, the .EXE is preferable**: it installs easily and updates automatically.

**For large-scale deployment, the .MSI may be preferable for your IT team**. In that case, two options are available:

1. A simple installation without automatic updates, requiring reinstallation for each update.
2. A procedural installation with automatic updates.
   {% endhint %}

## Download

### .exe format

You can find the executable to install at the following link:

* Version 5.2.2 : <https://core.api.cogneed.ai/cogneed-dual-canal-application/win32/x64/cogneed-dual-channel-setup-5.2.2.exe>

### .msi format (without updates)

You can find the MSI to install at the following link:

* Version 5.2.2 : <https://core.api.cogneed.ai/cogneed-dual-canal-application/win32/x64/cogneed-dual-canal-application-v5.2.2.msi>

### .msi format (with updates)

To download Version 5.2.2, you will need the following three files:

* **Deployment MSI:**
  * This file corresponds to the new CogNeed executable. When run by your IT team, it installs a CogNeed application “installer” for your users and makes it available to all users on the machine.
  * Link: <https://core.api.cogneed.ai/cogneed-dual-canal-application/win32/x64/cogneed-dual-channel-deployment-5.2.2.msi>
* **Example .ps1 file:**
  * This file is an example PowerShell script that checks whether the CogNeed “Squirrel” application is already installed and installs it if it is not.
  * Link: <https://core.api.cogneed.ai/cogneed-dual-canal-application/win32/x64/install-cogneed.ps1>
* **Example .bat file:**
  * This BAT file is an example file which, when run by your IT team, would make the PowerShell file available in your users’ environment and would launch the installation once the user is logged in.
  * Link: <https://core.api.cogneed.ai/cogneed-dual-canal-application/win32/x64/install-cogneed-task.bat>

## **Installation**

### **Installing the .exe or the .msi without updates**

To install the application directly on users’ workstations, without intervention from your IT department, you must have administrator rights and follow the steps below:

{% content-ref url="/pages/Xl3RwNp1T53TEtm26SJe" %}
[Installation](/cogneed-centre-daide/cogneed-help-center/dual-canal-application/installation.md)
{% endcontent-ref %}

### Installing the .msi with updates

The two files, “.ps1” and “.bat”, are intended to ensure that, with a simple machine-level installation of the provided “.msi”, the application is properly made available to all users, even in the event of workstation changes.

{% hint style="warning" %}
These two files were developed and tested in our environment for installation by an admin user for another user without administrator rights, but they should be used for reference purposes only. <mark style="color:$warning;">**It is likely that adaptation by your IT team will be necessary**</mark>.
