title: IT rollout
description: Install Kortix Capture on many Windows, macOS and Linux computers with one enrollment token. Each computer enrolls and records on its own, with no sign-in to Kortix, and you link it to a person when you want.
---

IT installs Kortix Capture, the separate recorder app, on every Windows, macOS
or Linux computer with one command. The installer adds a machine service. At
each sign-in the service enrolls the computer and starts recording. Nobody signs in to Kortix
by hand, nobody needs a Kortix account, and nobody can quit the recorder
except IT.

This page is for the IT team and the Kortix account admins. For one person on
their own computer, see [Capture → Install Kortix Capture](/docs/capture#install-kortix-capture).

## How it works

1. An account admin creates an **enrollment token** in Kortix.
2. IT installs `KortixCapture-x64.msi` on each computer with the Kortix URL and the
   token. The installer writes both to the registry and starts the
   **Kortix Capture** Windows service.
3. At each Windows sign-in the service reads the person's Windows sign-in
   name (the user principal name, for example `jane@corp.example`) and enrolls
   the computer with the token.
4. The computer gets a device token and starts recording. It belongs to the
   account. A personal token links it to its person. Any other computer
   records **linked to no one**, which is a normal state: an admin links it to
   a person when that is wanted.
5. The Kortix Capture icon in the notification area shows that it records.
   Nothing else interrupts the person. When the policy sets a notice, the
   person sees it once.

The service runs as `LocalSystem`. It starts the recorder in each signed-in
session as that person, and starts it again within seconds when it stops.
The enrollment token stays with the service: the registry key that holds it is
readable by SYSTEM and administrators only, and the person's processes never
see it.

## Before you start

- Turn on Capture for the account and set the policy: what is recorded, the
  frame rate, exclusions, retention and **the notice** the person sees. See
  [Capture → The policy](/docs/capture#the-policy).
- People do not need Kortix accounts. A computer records for the account
  whether or not it is linked to a person. To link computers to members as
  they enroll, turn on **Approve each computer**: Kortix suggests the member
  with the computer's sign-in email, and you confirm it.
- You need the `capture.manage` permission. Account owners and admins have it.

## 1. Create an enrollment token

In Kortix, open **Capture → Devices**, then **Company install**. Fill in:

| Field | What it does |
|---|---|
| Name | A name for the token, for example the computer group. |
| For | **Anyone at the company**: one token for many computers. They enroll linked to no one; you link them, or confirm the suggested member with **Approve each computer**. **A member**: a personal token. Every computer it installs links to that person, whoever signs in. It stops working when that person leaves the account. |
| Email domains | Anyone tokens only. Only people who sign in to the computer with these domains enroll. Empty: anyone. |
| Computer limit | A cap in case the token leaks. A personal token starts at 1. Empty: no limit. |
| Expires | 7, 30 or 90 days, or never. Computers enrolled before it expires keep recording. |
| Approve each computer | Every new computer waits for an admin, also when its person is a member. |

Kortix shows the token (`kortix_enr_…`) once. Copy it with the install
command next to it. Anyone who has the token can enroll computers into the
account until you revoke it, so handle it like a password.

From the API: `POST /v1/accounts/<account_id>/capture/enrollment-tokens` with
`{"name": "Pilot laptops", "email_domains": ["corp.example"], "max_devices": 20}`.
For a personal token, add `"user_id": "<member>"`: the member must belong to the
account, else the API answers `400` `capture_enrollment_invalid`.

## 2. Install on each Windows computer

Run as an administrator:

```powershell
msiexec /i KortixCapture-x64.msi /qn KORTIX_URL=https://api.kortix.com ENROLLMENT_TOKEN=kortix_enr_...
```

`KORTIX_URL` is the address of your Kortix API without `/v1`. Self-hosted
Kortix uses its own API address. The installer marks `ENROLLMENT_TOKEN` as
hidden, so it does not appear in installer logs.

With Microsoft Intune, add the MSI as a line-of-business or Win32 app and use
the command line above. With Group Policy or another tool, install the MSI
without properties and write the two registry values yourself:

| Key | Value | Type |
|---|---|---|
| `HKLM\SOFTWARE\Policies\Kortix\Capture` | `Url` | `REG_SZ` |
| `HKLM\SOFTWARE\Policies\Kortix\Capture` | `EnrollmentToken` | `REG_SZ` |

An upgrade (`msiexec /i` with a newer MSI) keeps the registry values when you
pass no properties.

## 3. Check the rollout

**Capture → Devices** lists every enrolled computer with an **IT rollout**
badge, under its person or under **Linked to no one**, with its live state:
recording, paused, offline. A computer reports within a minute of the first
Windows sign-in.

To link a computer to a person, choose **Link to a person…** on it. What it
recorded linked to no one moves to that person. See
[Capture → Link a computer to a person](/docs/capture#link-a-computer-to-a-person).

**Waiting for approval** lists computers that wait for an admin: the token
approves each computer, or an admin revoked this one. For each, choose
**Approve** (and, if you like, the person it records for) or **Deny**. An
approved computer starts recording within a minute.

On the computer:

```powershell
sc query KortixCapture
Get-Process kortix-capture | Select-Object Id, SessionId
```

The service is `RUNNING`, and a `kortix-capture` process runs in each
signed-in session.

## Remove a computer or stop a rollout

| To | Do |
|---|---|
| Stop new computers from enrolling | Revoke the token in **Company install**. Enrolled computers keep recording. |
| Stop one computer | Revoke the device in **Devices**, or deny it in **Waiting for approval**. Its device token stops working at once. The computer does not enroll again until an admin approves it. |
| Remove Kortix Capture | `msiexec /x KortixCapture-x64.msi /qn`. The service and the program files go away. Recordings on the computer stay in each person's profile until retention deletes them. |

## What the enrollment token can and cannot do

- It enrolls computers into one account, within its domains, limit and
  expiry. It cannot read anything.
- A device token, which each enrolled computer gets, uploads that computer's
  recordings and reads the account's policy. It cannot read recordings.
- The sign-in name a computer reports is not proof of who uses it: an
  administrator of that computer can change it. So the name never links a
  computer on its own. It is a suggestion you confirm under **Approve each
  computer**.
- An enrolled computer proves itself with its current device token when it
  enrolls again. A copy of its machine key alone gets a new token only after
  an admin approves it, for example after a reinstall.
- Every enrollment, token change and decision is in the account's audit log:
  `capture.device.enroll`, `capture.enrollment_token.create`,
  `capture.enrollment_token.revoke`, `capture.enrollment.approve`,
  `capture.enrollment.deny`, `capture.device.link`.

## Answers from enroll

The service shows these in its log (`%ProgramData%\Kortix\Capture\logs`) and
retries on its own.

| Answer | Means | The computer |
|---|---|---|
| `enrolled` | The token is valid. `member` names the linked person, or is `null` while the computer is linked to no one. | records |
| `pending` `approval_required` | The token approves each computer, an admin revoked this one, or it asked for a new token without its current one. | waits; asks again every minute |
| `401` `enrollment_token_invalid` | The token is unknown, revoked or expired. | asks again every hour |
| `403` `enrollment_domain_not_allowed` | The sign-in domain is not one of the token's. | asks again every 6 hours |
| `403` `enrollment_limit_reached` | The token reached its computer limit. | asks again every hour |
| `403` `enrollment_denied` | An admin denied this computer. | asks again every 6 hours |
| `403` `capture_disabled` | Capture is off for the account. | asks again every hour |

## macOS

IT writes the Kortix URL and the token to a root-only file, then installs the
package. The package installs `Kortix Capture.app` (Developer ID signed and
notarized), a machine service (LaunchDaemon) that holds the token and enrolls
each person who signs in, and an agent that records in every session.

```bash
sudo mkdir -p "/Library/Application Support/Kortix/Capture"
echo '{"url":"https://api.kortix.com","enrollment_token":"kortix_enr_..."}' | sudo tee "/Library/Application Support/Kortix/Capture/config.json" >/dev/null
sudo chmod 600 "/Library/Application Support/Kortix/Capture/config.json"
sudo installer -pkg KortixCapture-universal.pkg -target /
```

With an MDM, deploy the package and a configuration profile for the domain
`ai.kortix.capture` with the keys `Url` and `EnrollmentToken`. A profile is
readable by every user on the computer; use the root-only file when the token
must stay secret.

macOS asks the person to allow Screen Recording once. A Privacy Preferences
Policy Control (PPPC) profile can pre-approve Accessibility and Input
Monitoring for `ai.kortix.capture`; for Screen Recording it can only let a
standard user approve it. To remove Kortix Capture:
`sudo "/Applications/Kortix Capture.app/Contents/Resources/uninstall.sh"`.

## Linux

```bash
sudo install -d -m 755 /etc/kortix
echo '{"url":"https://api.kortix.com","enrollment_token":"kortix_enr_..."}' | sudo tee /etc/kortix/capture.json >/dev/null
sudo chmod 600 /etc/kortix/capture.json
sudo apt install ./kortix-capture_amd64.deb
```

The package installs a machine service (`kortix-capture-machine`) that holds
the token and enrolls each person who signs in to a graphical session, and a
user service that records in every session. Kortix Capture records X11
sessions; a Wayland session enrolls but records nothing yet. To remove it:
`sudo apt purge kortix-capture`.

Without the config file on macOS or Linux, each person chooses
**Sign in with Kortix…** from the Kortix Capture icon
([Capture → Install Kortix Capture](/docs/capture#install-kortix-capture)).
