FAQs

Can I use FAR 23 LOADS floating license like a node locked license?

Yes, you can . Do make sure you follow the installation instructions for a floating license and the WIBU-KEY is inserted into the local computer USB port.

The Theory and Examples Manual PDF asks for password when I try to open it. What do I do?

There is no actual password.  SmartShelter defaults to the password request when it cannot detect a license or after a recent update to Acrobat/Acrobat Reader. Make sure you use Adobe Acrobat Reader to open the Manual. Download the free Acrobat Reader DC or 11 from here if you need to. If you install Acrobat Reader after installing FAR 23 LOADS SmartShelter PDF Reader, you will need to un‑install and re‑install it. You can download a fresh copy of SmartShelter PDF Reader from Wibu-Systems. If you are using a floating license, please restart your license service. Go to your license host computer and type Services in the Windows Start button search box and click on Services under Programs or bring up a command prompt with administrator’s privileges and type services.msc. Look for WibuKey Server services and restart the service.

While installing FAR 23 LOADS software, I get an Error 1721. What do I do?

Installing FAR 23 LOADS software requires an administrator account or user with administrative rights. With a non-administrative user account, you can do so by right-clicking on the installer (setup.exe), select Run as administrator and provide the administrative credentials.

When using software, a Run-time error 55 or Run-time error 339 pops up stating: Component ‘comdlg32.ocx’, ‘tabctl32.ocx’ or one of its dependencies not correctly registered.

Proceed with the following remedies.

  1. For Windows 8 and above users, use Compatibility mode of Windows XP (any version) to run FAR 23 LOADS.
  2. The permission setting of the said ocx is the cause of the error message. Locate the ocx file in C:\Windows\SysWOW64 (or C:\Windows\System32 for a 32-bit computer) and modify the Users group such that the group has permission to Read, Read & execute.
  3. If necessary, download comdlg32.ocx and tabctl32.ocx files. Save the ocx files and copy them to C:\Windows\System. If you prefer to download from Microsoft, click here. With an elevated command prompt, type
    cd\windows\system
    ..\syswow64\regsvr32 comdlg32.ocx
     (..\system32\regsvr32 comdlg32.ocx for 32-bit computer) and/or
    ..\syswow64\regsvr32 tabctl32.ocx (..\system32\regsvr32 tabctl32.ocx for 32-bit computer)
    A message should pop up and state DllRegisterServer in ocx succeeded

Software Licensing

DARcorporation uses Wibu-Systems WibuKey copy protection for the FAR 23 LOADS licensing. The WibuKey concept consists of a WibuBox and the Wibu software. The WibuBox or WibuKey refers to the USB dongle that contains the software license. Our software needs the license to be present so that it will run. The Wibu software (or drivers) refers to the Wibu program that must be installed so that the computer can recognize WibuBoxes.

FLOATING LICENSE: Software is accessible from multiple computers, but limited to the number of licenses purchased. The WibuKey does not need to be attached to the local computer where the software is started. All computers running FAR 23 LOADS must be able to access the license server.

NODE LOCKED LICENSE: Software can only be used on the computer the software is installed on. The WibuKey must be attached to the local computer where FAR 23 LOADS is started.

System Requirements
