### Command Line Installation

1. Download Twosense Installer MSI. The link will be provided by your Twosense account manager.
2. Open a Command Prompt or PowerShell (**as Administrator**), and navigate to the file path where the MSI file is located.
3. Enter the following command (replace with the appropriate MSI filename and parameters):\
   \
   `msiexec.exe /i TwosenseAuthenticator-x.y.z.msi /qn+ IKEY="[your key here]" SKEY="[your key here]" GROUPID="[your group id]"`\
   \\

   **Parameters:**

   * **IKEY**: Your integration key. (Required)
   * **SKEY**: Your secret key. (Required)
   * **GROUPID**: The group ID for the machine. (Optional)
   * **IGNORERDP**: Set to *1* to bypass Twosense when logging into the machine via RDP. If set to *0* or left unset, Twosense will operate normally during RDP login. (Optional)
   * **SKIPVALIDATION**: Set to *1* to bypass installation validations. If set to *0* or left unset, the installer will run its normal validation checks, which include verifying that the IKEY and SKEY are properly configured and validated. (Optional)

   **Notes**

   * The values for parameters `IKEY`, `SKEY`, and `GROUPID` are **case-sensitive**.
   * To disable showing the success/failure message post-installation, change the `/qn+` to `/qn`.
   * To enable logging add `/l*v twosense-installer-log.txt` to the end of the command. You can specify a different filename or path as needed.
4. Reboot after the installation has finished.

### Validation

To check that the installation was successful:

* After rebooting the machine, log in as any user.
* Open the Twosense portal at <https://app.twosense.ai/login>.
* You should see the login event on the Events page.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

```
GET https://docs.twosense.ai/windows-authenticator/guides/windows-installation-guide.md?ask=<question>&goal=<endgoal>

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
