V-Ray Could Not Obtain License

Here you can find the list of symptoms and their likely cause when V-Ray could not obtain the license. Please check the resolution part at the end of this section.

Symptoms:

When you try to render with V-Ray Standalone, an error message appears in the console: “Could not obtain a license (10061).”

Cause:

No access to the Chaos license server.

Symptoms:

When you try to render with V-Ray Standalone, an error message appears in the console: “Could not obtain a license (-98).”

Cause:

No available license on the Chaos license server. 

Symptoms:

When you start the V-Ray GPU render server, there are no error messages in the V-Ray console, but when a job is sent to the V-Ray GPU render server there is an error in the console "Could not obtain a license (10061)."

Cause:

No access to the Chaos license server.

Symptoms:

When you start the V-Ray GPU render server, there are no error messages in the V-Ray console, but when a job is sent to the V-Ray GPU render server, the error in the console is "Could not obtain a license (-98)."

Cause:

No available license on the Chaos license server.

Resolution:

Please go through the check-list below.

1. Checking the Chaos license server: 

Please restart the machine with the Chaos license server and dongle installed. Unplug the dongle and plug it again in a different USB port, preferably USB 2.0. Make sure that Windows properly recognizes the dongle and doesn't show error message. If you receive an error message, please refer to License Server Can't Start section.

Start the Chaos license server from Windows Start menu > All Programs > Chaos Group > Start Chaos license server.

You may receive a message warning that the Chaos license server is already running.

Open the link http:// localhost :30304 in a web browser on the same machine.

This will open the Chaos license server status web page. If it looks like the screenshot below, the license server is working.

2. Checking the available licenses on the license server: 
After you ensuring the Chaos license server is working, you need to check the available licenses. On the same machine, where the Chaos license server is running, open the link http://localhost:30304/getstatus 

Please refer to Chaos License Server Status section in the Set up your V-Ray License page for more information on the type of licenses you need to look for. 

If you do not see the V-Ray Standalone licenses, this means that your dongle has to be reprogrammed as described in Dongle reprogramming section in the Set up your V-Ray License page. If you don't see free licenses this means that all available licenses are in use and you can't have more concurrent users.

3. Checking the connection to the license server:

If V-Ray is on the same machine as the Chaos license server, you can skip this step.

To make sure that nothing is blocking the connection to the license server on the machine where you want to run V-Ray, open the link http:// <IP_address> :30304 in a web browser, where <IP_address> is the IP address of the machine with the Chaos license server. If you get a web page like the one below, V-Ray can access the Chaos license server from this machine. In the example screenshot below the IP address of the machine with the license server is 10.0.0.160

If you get an error message that the web page can't be accessed then there is a network problem that prevents the connection to the Chaos license server. If you have any firewall or antivirus software running on your machines make sure they are not blocking applications' access to the network or blocking the communication on TCP/IP port 30304. Please contact your system administrator for more information.

4. Checking the V-Ray license settings:

On the machine where you want to use V-Ray, run the V-Ray license client configuration utility from Windows Start > All Programs > Chaos Group > Change license settings. In the dialog that appears, make sure that the IP address in the License server field at the Primary license server tab is entered correctly and that the connection port is 30304. If you modify any of these settings, you will need to restart V-Ray Standalone.

Note: If the Chaos license server is running on the same machine as V-Ray you can use localhost or 127.0.0.1 in the License server field.

Chaos License Server Can't Start

Symptoms:  

When you start the Chaos license server it pops a dialog box like the one shown below:

Cause:  

This error message appears when the Chaos license server cannot find a dongle attached to the machine.

Resolution:

Before you start, make sure the dongle is NOT plugged-in.

1. Uninstall the WIBU-KEY driver from Windows Control Panel.

2. Update your USB drivers to the latest version.

3. Restart your machine.

4. Download and install the latest WIBU-KEY drivers from http://wibu.com/download_user.php.

5. Attach the dongle to a different USB port, preferably to USB 2.0. Make sure that Windows recognizes the dongle and doesn't show error messages. To verify that dongle is properly installed please go to the Windows Control P anel > System applet. Choose the Hardware tab and then click on the Device manager button. Expand the Universal serial bus controllers list and check for a WIBU-BOX/RU entry there:

Dongle Disconnects Periodically

Symptoms:  

The dongle is working for extended periods of time but periodically disappears for no apparent reason and is no longer detected by Windows as a USB device. This could cause the Chaos license server to fail or V-Ray licenses to be refused.

Cause:  

There can be a number of reasons related to the hardware configuration and Windows settings like the Power options.

Resolution:  

Please check your Windows Power Options, make sure that your USB devices are not powered off.

Try to plug the dongle into a different USB port on the same machine, preferably USB 2.0, and restart the Chaos license server. If you still experience problems, try to install it on a different machine.

Missing Chaos License Server Icon

Symptoms:  

The Chaos licensing server is running but there is no icon in the Windows System Tray.

Cause:  

The icon is hidden by the Auto-hide unused icons option of the Windows System Tray or the Chaos license server is registered as a Windows service.

Resolution: 

1. If you have the Auto-hide unused icons option of the Windows System Tray, click on the double-arrow icon to expand the full list of icons.

2. If you still do not see the Chaos licensing service icon, that means that the V-Ray licensing service is started as a Windows service and in that case it cannot show any graphical user interface. There is currently no resolution for this; you need to manage the Chaos license service from the Windows Control Panel > Administrative tools > Services applet.

Updating Dongles when the .rtu Files are not Associated Properly

Symptoms:  

WIBU-KEY drivers are properly installed, but double-click on the .rtu file doesn't update the dongle.

Cause:

The .rtu file is not associated properly with the WIBU-KEY drivers.

Resolution: 

Please, first try the steps from the Chaos License Server Can't Start section. If this doesn't help proceed with the steps below:

1. Make sure that the dongle is plugged-in.

2. In the Windows Control Panel locate the WibuKey management tool and run it: 
   
   
    

3. Now you need to start the Advanced Mode from the system menu by right-clicking onto the title bar. Go to the WibuBox Update tab. 
   
   
    

4. Click Browse, specify the .rtu file, and press Apply.

V-Ray GPU is Crashing

Symptoms:  

When rendering with V-Ray GPU on CUDA, it crashes without showing a specific error message.

Cause:

The scene you are trying to render is too large and the Graphics card memory is insufficient.

Resolution:

You can try to reduce the scene size by reducing the polygon count or by using lower resolution textures. V-Ray GPU has an option called Resize textures for GPU that you can use to automatically resize textures during rendering on the GPU.

Alternately you can upgrade your graphics device with one containing more memory.
