Activate Your CatWalk XT License

Aim

To activate a CatWalk XT license after purchase. Note that you do not need to follow this procedure if your license is on a USB hardware key.

Background Information

When you start CatWalk XT, the software checks that your license is valid. The license may be stored in your hardware key (dongle), in your CatWalk XT computer (Fixed license) or in the Noldus server (Floating license).

If no valid license is found, you can activate your license by following the procedure below.

Important Terms

• Activation key. An activation key is provided by Noldus to activate your license. You find an activation key on a letter or email sent to you.
• Computer key. A computer key comes into play when you activate your license offline. This is a key that identifies the computer that you are using during activation.
• License key. A license key is the unique piece of information that you obtain after you activate the license. You can find this key in CatWalk XT by choosing Help > About CatWalk XT > License Info.

Prerequisites

• You have installed CatWalk XT.
• You have received a License Activation Key from Noldus.

What Do You Want to Do?

• Activate a fixed license (see below). Do this when you want to work with CatWalk XT on one computer only.
• Activate a floating license (see below). Do so if you plan to use this license on different computers at different times. If you have two or more floating licenses instead of one, you can use CatWalk XT on multiple computers simultaneously.

Activate a Fixed License

1. Start CatWalk XT. In the window that appears, choose Activate software license key.
2. Choose Fixed - On this computer only and click OK.
3. Enter or copy the Activation Key that you received from Noldus.
4. Select one of the following options depending on whether your CatWalk XT computer is connected to the internet:
   • Activate Online. Do so if your computer is connected to the internet. Next, click OK. A message appears that the license has been activated.
   • Activate Offline. If your computer is not connected to the internet, you need a smartphone connected to the internet that can scan a QR code. Note that the Activate Offline option is not available if you have purchased a time-limited license or received a license for a free trial.
     1. To obtain the Computer Key, scan the QR code with a smartphone.
     2. If the QR code is recognized, a web page of the Noldus License Manager opens that shows the required Computer Key.
     3. Enter this key in the Computer Key field in the CatWalk XT License Activation window and click OK.

Activate a Floating License

Choose a floating license if you want to use CatWalk XT on different computers (though not simultaneously). With two or more floating licenses, you can work with CatWalk XT on different computers and CatWalk XT systems simultaneously.

Important: You can only activate and use a floating license when your CatWalk XT computers are connected to the internet. Make sure that your CatWalk XT computer in the lab is always connected.

1. Start CatWalk XT on one of the computers. In the window that appears, choose Activate software license key.
2. Choose Floating - On multiple computers and click OK.
3. Under Activate floating license, enter or copy the Activation Key that you received from Noldus. Next, click OK.
4. The license is activated. You can start using CatWalk XT.
5. Repeat the procedure on the other computers.

Notes

• You cannot activate a term license after the expiration date.
• If activation fails:
  • Try once again and make sure that you enter the correct Activation Key and Computer Key, including capital letters and dashes.
  • Contact Noldus to obtain a valid Activation Key.
• If your license is not activated, you can still start CatWalk XT and work in unlicensed analysis mode.

Deactivate a CatWalk XT License

Aim

To deactivate a software license, either to end the license agreement or to transfer the license to another computer.

Example: You have purchased a new computer and you would like to transfer your CatWalk XT license from the old computer to the new computer.

Prerequisites

• CatWalk XT is running with a software license (no hardware key).
• The CatWalk XT computer is connected to the internet, or you have a smartphone connected to the internet.

What Do You Want to Do?

• Deactivate a fixed license (see below).
• Deactivate a floating license (see below).

Deactivate a Fixed License

1. In CatWalk XT, choose Help > Deactivate License.
2. Choose Fixed - On this computer only and click OK.
3. Select one of the following options depending on whether your CatWalk XT computer is connected to the internet:
   • Deactivate online. Do this if your CatWalk XT computer is connected to the internet. Select this option and click OK.
   • Deactivate offline. If your computer is not connected to the internet, you need a smartphone connected to the internet that can scan a QR code.
     1. Select this option and click OK.
     2. A QR code appears on the screen.
     3. Scan this code using a smartphone and follow the link within 24 hours.
     4. Click Deactivate on the screen that appears in your browser.
4. CatWalk XT shows a message that the license has been deactivated and closes.

Notes

• If your smartphone is not connected to the internet, leave the link open, go to a place where your smartphone is connected to the internet, and open the linked page.
• When you click Deactivate offline, your license is deactivated on your computer but not yet on the Noldus server. For this second step you must scan the QR code, follow the associated link, and click Deactivate in a web browser on your smartphone. Do this within 24 hours.

Deactivate a Floating License

Deactivate a floating license when you need to transfer that license to another computer. Note that when you have floating licenses, in order to be able to work on one computer you just need to close CatWalk XT on the other computer(s). You do not need to deactivate the license on the other computer(s).

1. Make sure that the CatWalk XT computer is connected to the internet.
2. In CatWalk XT, choose Help > Deactivate License.
3. A message appears: License successfully deactivated. CatWalk XT will close now.
4. You can now activate that floating license on another computer. Choose to activate a floating license as described in the Activate Your CatWalk XT License section above.

Turn a Floating License to a Fixed License

Aim

You may want to turn a floating license to a fixed license so you can use CatWalk XT on a computer without an internet connection.

Prerequisites

• You have a CatWalk XT floating license.
• You have an Activation Key for your floating license.

Procedure

1. Open CatWalk XT and deactivate the floating license. An internet connection is required for this step. See Deactivate a Floating License above.
2. After deactivation of the license, CatWalk XT closes.
3. Start CatWalk XT on the computer where you want to have the fixed license.
4. Choose Activate software license key, then Fixed - On this computer only. Follow the instructions under Activate a Fixed License above.

Turn a Fixed License to a Floating License

Aim

You may want to turn a fixed license to a floating license because you want to use CatWalk XT on multiple computers (not simultaneously). If you purchased multiple floating licenses, you can work on multiple computers simultaneously because a license will be active on each computer.

Prerequisites

• You have a CatWalk XT fixed license.
• You need to have the Activation Key for your floating license.

Procedure

1. Open CatWalk XT and deactivate the fixed license. See Deactivate a Fixed License above.
2. After deactivation of the license, CatWalk XT closes.
3. Start CatWalk XT on the computer where you want to activate the floating license. An internet connection is required for this step.
4. Choose Activate software license key, then Floating - On multiple computers. Follow the instructions under Activate a Floating License above.

Note: If you choose to deactivate offline, first click OK, then scan the QR code that appears. Follow the link and click or tap Deactivate.

Duration of the CatWalk XT License

A CatWalk XT license can be one of the following types:

• Perpetual license. This is the most common license. You purchase a copy of CatWalk XT on a one-time basis and can use the software forever.
• Time-limited license. This license is generally valid for a period of six or twelve months. A time-limited license can only be activated online.

CatWalk XT in Analysis Mode

Aim

To carry out analysis and visualization of already-existing track data in CatWalk XT without a license.

Background Information

A CatWalk XT license is needed whenever you acquire new data and record video. It is therefore important to activate a license on the computer that you use to collect data. However, you can also install the CatWalk XT software on other computers without a license.

Example: After collecting gait data in your lab with a CatWalk XT license, copy the CatWalk XT experiment to your laptop where you have installed CatWalk XT without a license. There you can visualize and analyze your data.

Procedure

1. If you have not done so yet, install CatWalk XT.
2. Start CatWalk XT.
3. If CatWalk XT does not find a valid license, a window opens with the message: No License key found.
4. Choose Start in unlicensed analysis mode.

What You Can Do with CatWalk XT in Analysis Mode

CatWalk XT in unlicensed analysis mode offers all the functions necessary to refine analysis and produce results:

• Open existing experiments.
• Edit the values of independent variables in the Trial List.
• Classify runs and adjust the Classification Settings.
• Create new Data profiles and select data.
• Create new Parameter profiles and select parameters.
• Use all the analysis functions under the Analyze menu.
• Export videos, visualizations, run data, all statistics, and charts.
• Make a backup of your experiment and restore experiments from backup files.
