All video cameras or archives stop working once the license maximum is reached

If the activation key allows the use of a smaller number of video cameras than the amount used at the moment on the system, all of the video cameras will cease to function with the system. To resume operation, remove the objects corresponding to the excess number of video cameras and restart the server.

Restart the Server through the Start menu as follows:

  1. All Programs -> C-Werk -> Shut Down Server
  2. All Programs -> C-Werk -> Start Server

Similarly, if an activation key allows using archives with a total size of an amount less than the current one, you are advised to correct the archive size to the required amount and then restart the server.

No signal from video cameras and failure to connect to other servers

If the Windows Firewall (or firewall of other manufacturers) was disabled during installation of C-Werk, C-Werk services and applications will not be automatically added to the list of firewall exceptions.

If the firewall is later turned on, this can interrupt the signal from video cameras and make it impossible to connect to other servers.

To solve this problem, add the following applications to the firewall exceptions: Apphost.exe, NetHost.exe, C-Werk.exe, and LicenceTool.exe.

If ESET NOD32 Smart Security 6 anti-virus software is used, disable Personal firewall

Incorrect display of Client interface elements

Client interface elements may be distorted on systems with some versions of GeForce drivers (such as 327.23, 337.88) installed.

In some cases this problem is solved by disabling stream optimization for the C-Werk.exe process:

  1. Run Control panel -> NVIDIA control panel-> 3D parameters-> Software settings.
  2. Click the Add button and select the C-Werk.exe file (<C-Werk installation directory >/bin).
  3. Set the Off parameter for the Threaded optimisation function.
  4. Click the Apply button.

If this solution does not eliminate the problem, then install an older driver for the graphics card.

Server error on Windows Server 2012

You may experience errors when running the server on Windows Server 2012. To fix the errors:

  1. Open the registry path HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\.
  2. Find the Windows parameter and change its value as follows: in the string "SharedSection = 1024,20480, 768 ", replace 768 with 4096. 
  3. Save the changes and restart the computer.

Emergency shutdown of the Client on Windows 8.1

You may see the Client shutting down on Windows 8.1 with an error: " The name of the failed module: KERNELBASE.dll Exception code: 0xe0434352 ".

In this case, please contact Microsoft support.

Error creating new archives even when license restriction on total size is observed

If the user creates archives at the same time (in other words, without applying changes) while deleting some existing archives, creation of archives may be forbidden even if the total archive size does not exceed the amount of the license restriction.

This happens because when verifying the license restrictions, the size of created archives is calculated based on the total size the last time when changes were applied

To regain the ability to create new archives in such situations, the user must first delete unnecessary archives and apply changes.

High CPU load during OpenGL software emulation

If your computer's graphics card does not meet OpenGL requirements (see Limitations of the C-Werk Software Package), OpenGL can be emulated in software.

But this may place a high load on the CPU.

Performance of C-Werk when working with NetLimiter 2

If NetLimiter 2 is installed in the system, there may be a significantly increased load on the processor when working with C-Werk.

This problem is resolved by removing NetLimiter 2.
