Installation

How to install the browser extension

For extension products only — desktop software users can just run the installer and skip this section

Download the extension package

Get the .zip file
1

Find the extension in the marketplace and click “Download” to download the .zip extension package file. Save it anywhere on your computer — do not unzip it, use the original .zip file as is.

📁
After downloading you will have a ShopCaiji_xxx.zip file — remember where you saved it
💡 Only download from official channels. Third-party packages may pose a security risk.

Open the extensions page

Go to extension management
2

Type one of the following into your browser's address bar and press Enter to open the extensions page:

🌐
Chrome: type chrome://extensions in the address bar and press Enter
🌐
Edge: type edge://extensions in the address bar and press Enter
💡 You can also reach the same page via the browser menu (top right) → More tools → Extensions.

Enable developer mode

Allow extensions to load
3

In the top-right corner of the extensions page, switch “Developer mode” on (it turns blue). Three new buttons will appear at the top — this is normal.

If the browser warns that “developer mode extensions will be disabled”, click “Keep enabled” — it will not affect normal use.
⚠️ Developer mode is required to load local extensions and does not reduce your browser's security.

Drag and drop to install

Finish the installation
4

Take the downloaded .zip file and drag it directly onto the extensions page and release the mouse. When the browser asks for confirmation, click “Add extension” to finish.

1
Open your file manager and locate the downloaded .zip file
2
Drag the file into the browser's extensions page and release the mouse when the blue drop area appears
3
A confirmation dialog appears — click “Add extension” to complete the installation
If drag and drop does nothing: unzip the .zip into a folder → click “Load unpacked” → select that folder
✅ Once installed, the extension icon appears in the toolbar at the top right. Visit the relevant site to see the extension interface.
Step by Step

License Rules

Licence terms of use

Please read carefully before buying — using the software means you accept these rules

🔒
Purchases of every tool are tied to your ShopCaiji account. After buying you can check the key and remaining time at any time under “My licences” in the top right.
🖥️

One licence per machine

Each licence key can be bound to one device only and cannot be used on several computers at the same time.

Strictly enforced

Automatic sign-out

The system monitors heartbeats in real time. Running one licence on several devices signs the other one out automatically, without warning.

Real-time monitoring
🔄

Device changes allowed

After switching computers you can move the remaining time to the new device under “My licences” — no need to buy again.

Supported
🔢

Reset limit

Each licence key can be reset 3 times in total. After that it can no longer be rebound, so use them carefully.

3 in total
⚠️
Once the resets are used up you can no longer bind to a new device. Only reset after you are sure you are changing computers, so you do not waste them.
🚫
Lending, reselling or sharing licence keys is strictly forbidden. Doing so leads to a permanent account ban with no refund.
FAQ

FAQ

Check here first — most questions are answered below

Why do I have to download the software before buying?
Because we use one key per device: the licence key is generated and bound to your hardware ID at the moment of purchase. You have to run the software first to get this computer's unique hardware ID, then enter it at checkout so the licence binds to the right device.
Where do I find the hardware ID in the software?
Install and run the software, then open the login / activation screen — this computer's hardware ID (HWID) is shown automatically and can be copied directly. Both the desktop app and the browser extension show it in the activation dialog.
Nothing happens when I drag the .zip file — what should I do?
First make sure “Developer mode” is switched on. If nothing still happens, use the fallback: 1. unzip the .zip into a folder; 2. click “Load unpacked” on the extensions page; 3. select the unzipped folder to finish the installation.
Where can I see my licence key?
The licence key pops up on the page as soon as payment succeeds. You can also sign in to your ShopCaiji account and click “My licences” in the top right to see the keys and remaining time for every product you have bought.
What if I change computers?
Go to “My licences”, find the key, click “Reset and generate a new key” and enter the hardware ID shown by the software on the new computer. Note that each key can be reset at most 3 times in total, so use them carefully.
Can I use it on two computers at once?
No. The system uses real-time heartbeat monitoring: if one licence is signed in on two devices, the newer session signs the older one out. To use several devices, buy a separate licence for each.
What should I do if activation fails?
Please check: 1. the licence key was copied in full with no extra spaces; 2. the hardware ID matches the one you entered when buying; 3. your internet connection works. If that does not help, contact official support with a screenshot of your key and hardware ID.
Can I still change devices after using all 3 resets?
Once the resets are used up the system no longer allows self-service rebinding. Contact official support and explain your situation — they will handle it manually case by case.
