How-to activate your BackyardEOS or BackyardNIKON purchase or trial key


Here is a quick how-to on how to get and activate your BackyardEOS or BackyardNIKON purchase or trial key.

First Step, getting your key:

  1. Create an account here on otelescope.com.
  2. If you already have an account please sign-in now.
  3. Go to our store and add a Trial, Classic, or Premium edition in your cart and proceed to checkout.
  4. Your key will be issued immediately once the checkout is complete.
  5. You can access your key from the website top menu bar under "My Purchases -> Orders".

You need to go through this process even for trial keys.  This is because the act of going though the checkout process will instruct the activation server to generate and assign you a key.  You WILL NOT be asked to enter a credit card for a trial key.


Second Step, download your software and initial activation:

  1. If you are not already signed in please do it now; you can only download BackyardEOS and BackyardNIKON if you are signed in.
  2. Go to the download page and download your software.
  3. In some cases your anti-virus may give you a warning, this is a false positive.  All downloads from the otelescope.com website are 100% virus free.
  4. Install and start your software; enter your activation key and identifier as they appear in "My Purchases -> Orders" when prompted.
  5. Note that the identifier is case sensitive so make sure to respect upper and lower case in your identifier.

NOTE: If you already have a trial installed on your computer you DO NOT need to download again (unless a new version has been released and you wish to install the latest version).  You can keep the same version and follow the instructions in the third step below to activate your new purchase key.


Third Step, activating a purchase key when a trial is already installed:

  1. Start BackyardEOS or BackyardNIKON on your computer.
  2. If your trial key has already expired you will be prompted to enter your purchase key automatically.
  3. If your trial key has not expired you will not be prompted to enter a purchase key.  Instead start BackyardEOS or BackyardNIKON and click on the padlock icon in the upper right corner then click "Edit Activation Key" and enter your purchase key there.
  4. Restart BackyardEOS or BackyardNIKON and your new key will be activated.

Hope this helps,

I should also say that the How-To Forum is not the place to ask questions. If the How-To information did not address your question or solve your issue, you should have posted to a new thread in the BYN Forum (or the BYE Forum for a Canon camera).  The vast majority of users do not have a problem validating their license, but if everyone who did replied to this post then it would be difficult for any reader of the thread to find help for their issue.


I beg to differ. But noted with thanks.
