Licensing by Dongle

Dongle

During Installation & Activation, Follow These Steps Carefully
1. Install and run ZW3D using Administrator properties.
2. Ensure that you first plug the dongle into the computer's USB port, and then wait until its status light is steady (not flashing). Only then should you open ZW3D (stand-alone edition) or ZW3D Network License Server (network edition).
3. If the light on the dongle blinks, then it indicates a problem. Try the following solutions:
• Try moving the dongle to another USB port, or even try ZW3D and the dongle on another computer.

Error Message: Registration Failed

Q: I input the license code and then clicked Register button, but then I received a message that looks like this:

\

A: Enter the correct license code. Ensure that the code's version number matches the version of ZW3D you are registering. For example, if the license code is from the 2010 version, then it cannot be used to register ZW3D 2011. If necessary, you can email us at zw3d@zwsoft.com and provide us with your product ID, license code number, and the version of ZW3D. We will confirm the correct numbers.
 

ZW3D Shows Trial Version after Registration

Q: Why does my copy of ZW3D continue to show as the trial version, even after it showed the successful registering message?
A: Ensure you restart ZW3D after activation.
 

Network version

Server

Serial Number is 0

Q: Why does the serial number in the console of the license server show 0?
A: This may result from any of the following reasons:
  • The USB port is broken. Try moving the dongle to another USB port, or even try the dongle on another computer
  • The dongle is broken. Contact zw3d@zwsoft.com to obtain a replacement dongle.
 

Error Message: License Code Does Not Match

Q: I entered the license code and then clicked the Register button, but then I got a message that reads, "License code does not match!"

 
\

 
A: Check for the following possible errors:
1. Does the serial number show 0, or does it consist of an eight-digit number? Normally, it should be an eight-digital number. If it is 0, please refer to "Serial Number is 0" above.
2. If the serial number is eight digits long, check whether the version number of the ZW3D Network License Server matches the version of the license code you entered. For example, if you have a license code for the 2010 version, then you should install the ZW3D Network License Server of the 2010 version.
Solution:
The solution is to uninstall the current ZW3D Network License Server and then install the correct version that matches the version of the license code. Download corresponding ZW3D Network License Server from http://www.zwsoft.com/download or ask zw3d@zwsoft.com for the download link.
 

Unable to Activate ZW3D on the Server?

Q: Why can I not activate ZW3D on the server?
A: Ensure you followed these steps:
1. After getting the successful registering message, click the Start button, as illustrated below.

\
 2. After clicking OK, restart ZW3D.

Workstation

Workstation Cannot Get License From Server

Q: Why can the workstation not get a license from the server?
A: Ensure you received the successful registration message on the server, and that you clicked the Start button on the Network Server to start licensing. These two points are very important.
If the workstation still cannot get a license, check the following areas:
1. It may be that your computer's firewall software is blocking access to the licensing through the network. The solution is to add ZW3D and its port number to the firewall's exception list on both the workstations and server. Follow these steps:
a. Click Start -> Control Panel -> Windows Firewall.
b. On the server, make the changes shown by the figure below:

\

c. On the workstation, make the changes shown below:

\

d. Add the port number to the firewall's exception list, both on the server and workstation:

\
 
2. The copy of ZW3D installed on workstation may have a version number that is higher than version number of the ZW3D Network License Server installed on the server. Only a higher numbered version of a network server can license a lower (or equal) version of ZW3D on the workstation. For example, the ZW3D 2010 Network License Server is able to license to ZW3D 2010 and ZW3D 2009, but not ZW3D 2011. The solution is to download the corresponding ZW3D Network License Server from http://www.zwsoft.com/download or ask zw3d@zwsoft.com for the download link.
 

3. The server and the workstation are not in the same network segment. The solution is to modify the IP [Internet protocol] addresses of the server and workstation and to make sure that they are in the same network segment. For example, if the IP address of the server is 192.168.0.5, then the IP address of the workstation should be in the range of 192.168.0.1 to 192.168.0.254.
 

4. The workstation is not in the IP address range of the licensing group. The solution is to add the workstation's IP address to the IP range allowed to obtain licenses. See figure below.

\

\
 

5. Anti-virus software is blocking the program from running. The solution is to add ZW3D as an exception, to remove ZW3D from the isolation list, or even to turn off the anti-virus software.
 

6. The network license server is locked. The solution is to choose the Lock server option again to turn off the locking.

\
 

 

7. You have exceeded the maximum simultaneous connections for operating ZW3D. There are two ways to free licenses:

On the workstation, close the ZW3D program free the license for another user.
Take back a license by force. To do this, follow these steps:

a. Lock the server by choosing Lock Server from the Edit menu (or by clicking the Lock Server button on the toolbar). See figure below.

\
 

b. In the main window, right-click the name of the user license, and then click Kick out.
