After payment has been accepted, your activation key will be sent by email to the address that you provided in the purchase process.

I purchased the software but now I want a refund. How do I get a refund?
Unfortunately it is not possible to get a refund. For this reason, we offer a full-featured trial, so that you can fully test the software before purchase and decide whether or not it meets your needs.

How does the licensing work?

The activation key which you will receive by email after purchasing your license will allow you to activate the software on up to three of your personal computers simultaneously. The email also contains the instructions explaining how to activate for the first time. Keep it safe since you will need it if you need to activate in the future on a different computer. Your license status will be checked automatically at regular intervals, so be sure to connect your PC to the Internet at least once a month. You can move your licenses between different computers by clicking on the “Deactivate” button inside the “About” tab. Follow the process through to the end to receive your confirmation that the deactivation was successful. You can then activate again on a different computer.

Will the license expire?
No, the license is permanent, although there will be regular automatic checks of the license, so make sure to connect to the Internet at least once a month.

Do I need an Internet connection?

Yes, you need an Internet connection to start your trial period and to activate for the first time. In addition, you’ll need to connect to the Internet every now and again (at least once a month) in order to allow the software to perform its automatic license check

I lost the email that contains my activation key that was sent to me when I bought the product. How can I retrieve it?
Your license was purchased using the 2checkout payment gateway, which keeps track of all your purchases made via the gateway. To retrieve your activation key, go to and login to myAccount using either the email address you used to make the purchase or the Order ID. Once you enter into your account, click on the “My Products” page to recover the activation keys for all your purchases.

I own two PCs. Can I use the product on both of them at the same time, without needing to purchase another license?

Yes, you can activate your license on up to three of your personal computers using the activation key which was sent to you when purchasing the software.
My friend likes the product and wants to use the product on his PC. Can I use one of my activations to activate the product on his PC, so he can use it?
No, the license is individual and it is not permitted to use your activation key to activate the software on other people’s computers.

I have some friends who also want to buy the product. Can we get a discount if we purchase the product together?
Yes. On the purchase page, click on the “Volume discount prices” link just below the product name. You will see that there is a 5 Euro discount per license if purchasing between 3 and 9 licenses, and a 10 Euro per license discount if purchasing 10 or more licenses (or the equivalent in your currency of purchase). If purchasing multiple licenses, you will receive multiple activation keys by email, so the person receiving the email will have to pass the activation keys to each person who has purchased the license.

Is my license transferable to another person?
No, the license is individual and cannot be transferred to another person.

I have a valid license, but when I started my PC today, the screen reader kept saying “Please register this product”. What is the problem?
If you do not connect your PC to the internet for more than a month, then the regular license activation check will not be able to be done and the license will expire. If this occurs, connect your computer to the Internet, open the application and follow the steps to re-activate your license.

I’m selling my PC and buying a new one. Will I need to buy a new license for the new PC?
No. All you need to do is deactivate your license on your old computer (in About > Deactivate) and once you receive your confirmation message, the license will be deactivated and you can then reactivate it on your new computer.

My hard drive crashed and needed to be reformatted. Will I lose my license?

No, as long as you re-install the same licensed operating system as before. All you need to do is reinstall the software and register it again and the previous license will be recovered.

My PC was stolen. Will I lose my license?

Since you could not deactivate the license on the stolen PC, one of your three licenses will still be associated with your old PC. However, you can still use one of the two remaining licenses to activate the product on your new PC. In case of problems, please contact Code Factory’s customer support by opening a ticket.

I’m going to upgrade/format the hard drive, or change the operating system of my PC. Do I need to do anything before making this change?
Yes. Before making any major change to your PC (e.g. replacing/formatting the hard drive, upgrading the operating system, changing the processor), you should deactivate your license. After making the change to your computer, re-install and activate the software using the normal procedure.

How can I open the Windows Speech control panel to select Eloquence for Windows as my default TTS?
It is located in a different place, depending on the version of Windows that you have (often you can find it under the “Ease of Access” option in the control panel). One universal way to access it is to type the following into the Run prompt (which appears as an option after right clicking the Windows Start button): %windir%\System32\speech\SpeechUX\sapi.cpl

Regarding Eloquence for Windows: I’m going to the public library today to spend a few hours working on a public PC. Can I use one of my activations so I can use the app on the library PC?

Yes. You’ll first have to install Eloquence for Windows on the public PC (for example via the download web page, or by copying the installation file to a pen drive and installing it on the public PC). Once installed, you’ll be able to use one of the three activations associated with your activation key to temporarily activate the license on the public PC. WARNING: it is very important to remember to deactivate the license when you are finished working on the public PC, since otherwise one of your three activations will remain associated with the public PC and you will not be able to use it.

On what other platforms do you offer Eloquence?

Is the User Dictionary compatible with your Android versions of ETI-Eloquence and Vocalizer?
