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

Image Added

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.

Image Added

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:

Image Modified

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

1. from Windows C

1. ontrol Panel.

2. Update your USB drivers to the latest version.

3. Restart your machine.

4. Download and install the latest WIBU-KEY drivers

1. from http://wibu.com/download_user.php.

2. 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

1. the Windows

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

1.  Auto-hide unused icons

1.  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

1. 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

1. Chaos license service from

1. the Windows Control Panel

1.  > Administrative tools

1.  > Services

1.  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

1. the Windows Control Panel

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.
