How to Set Up Your Claude Unlimited License Step by Step

What You Need Before You Start

This guide walks you through setting up your Claude Unlimited license step by step. By the end, your account will be active and ready to use on your device of choice. You only need the license key from your Nexys order and an internet connection. Nothing else is required.

Claude Unlimited is built for developers who need long context windows, researchers working through heavy material, and power users who want no token caps. If that sounds like you, the setup below takes about five minutes.

Step 1: Find Your Delivery

Log in to your Nexys account and open the order that contains your Claude Unlimited license. Your purchase details and product key are delivered to the order page and to the email on your account. Copy the key exactly as shown, including any dashes or spaces.

This is where people most often go wrong. Copy the key from the delivery screen rather than retyping it. A single mistyped character will make activation fail.

Step 2: Open the Product and Activate

Open the Claude app or the web interface where your license is redeemed. Use the exact option the product page names for your platform. Paste your key in place, then confirm. The process is the same whether you are setting up on one device as the primary or plan to move it later.

Activation normally completes within a minute. If the screen sits loading longer than that, close the tab and try again once.

Step 3: Check That Activation Worked

Once activated, open a simple prompt and confirm you can send messages with no usage limit warning. That is the fastest sign the license is live. You should also see your active status reflected in your account area, usually under your subscription or plan details.

If you set the license up on more than one device, repeat the check on each one. Confirm each one shows the same active status.

Device and Reactivation Limits

Your Claude Unlimited license covers a set number of devices. When you switch to a new device, you typically reactivate on it rather than buying again. Check the product page for how many devices your key covers before you start moving it around.

If you hit the device limit, the usual fix is to deactivate the license on a device you no longer use, then activate on the new one. That keeps you within your allowed count instead of getting blocked at setup.

What a Failed Activation Looks Like

A failed activation usually shows an invalid key or doesn't work error. Before anything else, confirm you pasted the key without extra spaces and without dropping a character. Paste the key fresh from your order page rather than from a notes file that might have reformatted it.

If the key pastes correctly and still fails, it may be a regional or compatibility issue tied to your setup or location. Note the exact error message, because that is what the store needs to help you fast.

When a Key Does Not Work After Delivery

A license key that will not activate is a legitimate problem, and the Nexys refund policy covers it. If we cannot resolve your activation issue, you are entitled to a refund for that product key. The key point is to contact us with the exact error text and your order number so we can act quickly.

Our general policy is that all digital sales are final, so this situation is the exception rather than the rule. It is a real protection when a delivered key is defective, not a blanket return option.

What to Do If Setup Still Fails

Try these in order. First, copy the key again straight from your order page. Second, check that you are on a supported device for the platform. Third, reach out through the contact method on the product page and include the full error message and your order number.

In most cases a fresh copy of the key resolves the issue on the spot. If the problem is on our side or the key itself is defective, the refund policy applies as described above.
