Please Read These Tips for Successful Installation & Installation.
Install and run ZW3D under Administrator privileges.
Ensure your computer's system time matches the current time.
To use your ZW3D license on another computer, remember to first return the license from the original computer. (You do not need to uninstall ZW3D from the original computer, only to return its license.) Your license can then be used on the other computer.
Remember to return the license before reformatting your computer's hard drive, reinstalling the operating system, or making major hardware changes – such as adding an internal hard disk, replacing the graphics board, or adding more RAM.
Invalid activation ID:
Q: ZW3D failed to activate. I received the message, "Invalid activation ID!"
A: This message may occur due to one of the following reasons:
Please ensure that you entered the activation ID correctly. Pay special attention to 0 (zero), O, 2, and Z. (As you know, 0 looks similar to O, and 2 looks similar to Z.) We suggest that you input the activation ID by copying and pasting it, if possible.
The license code may be out of date. Generally all activation IDs we provide are permanent, so this problem occurs rarely. But we also provide some activation ID for testing purposes, which are valid for a specific period of time, such as one or two months. You can check the validity of your ID by logging on to the ZW3D activation self service center (http://support.zwcad.net:8888/flexnet/operationsportal/showActivationIdLogon.do).
Error returned by the Operations server:
Q: ZW3D failed to activate. I received the message, " Error returned by the Operations server."
A: This message may occur due to one of the following reasons:
When activating online, the computer needs to connect to the ZW3D License Center. This message indicates that either the computer is not connected to the Internet, or that it was unable to connect to the ZW3D License Center through the Internet.Try to activate the software manually in the same manner as if the computer is not connected to the Internet. (An Internet connection is required only when clicking the Activate button for online activation. The computer does not need to be online when running ZW3D at any other time.)
If the computer connects to the Internet by proxy server, Please ensure that the proxy server is working.
Incorrect Quantity of Licenses
Q: The ZW3D License Manager failed to activate, and I received this message: "Quantity of licenses is incorrect! Please check".
A: The quantity you input should not be greater than the quantity of licenses you purchased, or the available copies remaining. You can check the number of licenses remaining for your network activation ID by logging in to the ZW3D Activation Self Service Center.
For instance, the figure below shows that the activation ID is licensed for five copies and that two of them have been activated.
Input the correct quantity (or the correct number remaining).
Failed to Get License from Server
Q: Why did the workstation fail to obtain a license from the server, even through the server was activated successfully?
A: The failure may be due to one of following reasons.
The server was not configured to start.
After activating the server successfully, you need to configure the Network Server to start distributing licenses to ZW3D on workstations. When you have configured the server and started it successfully, you will receive following result by clicking the Perform Status Enquiry button on the Server Status tab.
To configure the server, please follow the instructions in the Configure License Server section of the Help documents.
The workstation is not connected to the server.
Try to connect to the server. You can check the connection between server and workstation by pinging it. (Click Start, choose Run, enter ping and the server's IP address.)
The number of licensed running on workstations equals the maximum number of available licenses. For example, if you purchased five copies with your network license code and five workstations are already running ZW3D, then no more licenses are available. The sixth workstation will not be able to run ZW3D.
Free up licenses by one of the following methods:
A. Let one workstation quit ZW3D to free up its license.
B. Contact ZWSOFT to purchase more licenses for your activation ID. We can increase the licenses included with your network license code, or provide you with a new code that includes more licenses. But you must RETURN the license code to us before we can change it.
The operating system's firewall may be blocking licensing on the server or workstation.
On the workstation, add ZW3D and its port number (27000, by default) to the firewall's exception list. On the server, add ZW3D Network License Manager and its port (27000, by default) to the firewall's exception list.
On the Windows taskbar, click the Start button. Choose Control Panel, and then choose Windows Firewall. On the server:
On the Workstation:
Both on the Server and the Workstation:
Anti-virus software may be blocking the program from running.
Add ZW3D to the exception list, or remove ZW3D from the isolation list. In some rare cases, it may be necessary to turn off the anti-virus software completely.
The Options file may be restricting the workstation from obtaining a license from the ZW3D Network License Manager. The Options file manages licenses over the network. The workstation cannot get a license if the Options file blocks it.
You can open the file in Notepad. (The file is located on the installation path of the ZW3D Network License Manager, such as D:\Program files\ZWLMS.) The workstation cannot get a license when it blocked by the contents of this file, as shown by the following entry in the file:
Exclude ZW3D internet 192.168.0.5
This means that a workstation whose IP (Internet protocol) address is 192.168.0.5 is prevented from obtaining a license from the server. If you have never modified the Options file, then it will contain no restrictions. If you are unsure about the settings in the Options file, please refer to the Help documents: Soft Key Activate ->Network Version->Learn About Your License->Managing the Options Files->Option Files Syntax
, or email a copy of the Options file to us at firstname.lastname@example.org
7. There may be a difference in system time of more than 24 hours between the workstation and the client. Please correct the time on workstation and the client, and keep them synchronous. At the very least, ensure the time difference is no more than 24 hours.
