Activate your StackRegent license
Three ways to enter an SR- license key, what happens when you do, and how to read the License Information page afterwards.
Before you start#
A StackRegent license key looks like SR-XXXXX-XXXXX-XXXXX-XXXXX. You find it in the welcome email and on the license's service page in the client area. One key licenses one server: at its first successful check, the key is bound to that server's Windows machine ID. Trial keys from the free trial work the same way, for 10 days and 3 subscriptions.
The server needs outbound HTTPS to panel.stackregent.com and a correct clock. Keys bought earlier at system.coreinto.com keep working; the panel asks the server that knows its key.
Step 1: Choose how to enter the key#
Pick the one that suits you:
- With the installer. Pass
-LicenseKey SR-...to the one-line installer or toinstall.ps1. The installer checks it once the panel runs and masks it in the install log. - In the panel. Go to Tools & Settings › License Information, click Enter key (or Change key when one is saved), type it in Licence key and click Save and check.
- On the command line. In an elevated PowerShell, run
& "C:\Program Files\StackRegent\bin\stackregent.exe" license-set SR-XXXXX-XXXXX-XXXXX-XXXXX. To keep the key out of command history and logs, set the environment variableSTACKREGENT_LICENSE_KEYand runlicense-setwithout an argument.
Step 2: Let the panel check it#
The panel asks the license server at once. A new key is saved only when the license server accepts it. If the panel already has a working license, a key that cannot be checked leaves the current one in place, so a typo never takes a working server down.
Step 3: Read the License Information page#
Tools & Settings › License Information shows:
| Field | What it tells you |
|---|---|
| State | Licensed, Grace period or Restricted, with the license server's message |
| Edition | Your plan; trial licenses carry a Trial badge |
| Subscriptions | Subscriptions in use and the limit of your plan |
| Valid until / Works until | When the current check expires, or when the grace period ends |
| Next payment due | The service's next due date |
| Last successful check and Last problem | When the license server last answered, and the last error |
Click Check now at any time, for example after a renewal. From the command line, stackregent license-check does the same and prints the state.
After activation#
The panel checks the license every 24 hours at a random minute. If the license server cannot be reached, it retries after an hour and then every 6 hours, and keeps working through the grace period meanwhile. Every plan includes every feature; the plans differ only in how many subscriptions they allow. When you reach the limit, new subscriptions are refused with a message naming it, and existing ones are never touched; see renew or upgrade your license.
If the state reads Restricted, see license restricted mode. The licensing chapter of the administrator guide has the full reference. Anyone can check whether a server is licensed at stackregent.com/verify-licence.
Frequently asked questions
Where do I find my StackRegent license key?
In the welcome email sent after your order, and on the license's service page in the client area at panel.stackregent.com.
Can I use one StackRegent license on two servers?
No. A license key is bound to one server's Windows machine ID at its first check. Each server needs its own license; a license can be moved to a new server by reissuing it.
Does StackRegent need internet access for the license?
The panel checks the license once a day over HTTPS. Short outages do no harm: the panel keeps working until the check expires and then through a grace period, with a banner showing the date.
