"I guarantee that I entered it correctly according to the email address and license code you sent me, but the software still prompts me that the licensed email or license code is invalid. Why?"

If you have failed to register the software due to the invalid licensed email (registration email) or license code (registration code, license key) prompted by the software, please check the reasons below and follow our proposed solution to fix it.

Part 1. Why is the licensed email or license code invalid?

When you register the software, you may be popped up with one of the following prompts to remind you that the license code is invalid. This may be caused by the following reasons:

1. The most common cause is input errors. Please double check to confirm that the license code and licensed email you entered are correct, including the upper case and lower case. We recommend that you directly copy and paste the email address and license code to avoid spelling errors. In addition, please make sure that no spaces are added before and after your code.

2. Check if you ordered or downloaded the wrong product, because some products have similar names.

3. You may have confused the Windows and Mac versions of the product. Most products have two versions of Windows and Mac. They are two completely different products, each with its own license code.

4. You may have registered the software that you did not want to purchase from the toolbox. For example, when you run MobiKin Doctor for Android, the first main interface is a toolbox that contains many different separately charged software. Each individual software has a separate license code. So you may have mistakenly registered other non-purchased software from the toolbox.

Part 2. How to solve the problem of invalid licensed email or license code?

Based on the above reasons, we provide the following solutions:

1. In order to prevent input errors, please make sure that you enter the licensed email and license code, not the license name and license code. It is best to copy and paste the license code directly to prevent entering incorrect characters and leaving blanks before and after it. To confirm your licensed email and license code, you can check them with the email from support@2checkout.com, titled as "Your order on www.mobikin.com/: Product and payment information".

- Use the recipient's email address to confirm your licensed email.

- Check your license code in the "Product / Subscription Information" section of this email.

2. If you ordered a wrong product by mistake, please send an email to support@mobikin.com to get in touch with us. If you downloaded a wrong product, please re-download the correct product from our website.

3. Make sure that the program you are using is the same as the program you purchased, such as the full name of the program on Windows or Mac.

4. Make sure you are registering the correct software and that you've purchased. Please be noted that the Windows and Mac versions of the software do not share the same license code.
