Troubleshooting on Windows

This page troubleshoots some potential issues regarding successfully running a LabVIEW RCP VI under Microsoft Windows. Please review the following troubleshooting items about the Windows system configuration before contacting Quanser's technical support, which is detailed on the Technical Support help page.

This page describes and troubleshoots the following system configuration issues:

• If the NI DAQ device is Not Recognized in Windows: NI Driver Not Installed
• If 'NILVSim.dll' is Missing: LabVIEW Control Design and Simulation Module Not Installed
• If subVIs from '<vilib>:\Quanser\Rapid Control Prototyping Toolkit\' Cannot Be Loaded: Quanser RCP Toolkit Not Installed
• If Getting 'VI Missing' Messages when Opening a VI

If the NI DAQ device is Not Recognized in Windows: NI Driver Not Installed

This issue manifests itself if the NI data acquisition (DAQ) device is not properly recognized by the Windows Device Manager and shows up with a warning sign, as illustrated below.

This issue also causes Quanser RCP error 401226 (described in the Quanser Error Codes) when trying to access the unrecognized DAQ device with the RCP HIL Initialize VI.

To correct this issue:

• Ensure the NI-DAQmx drivers are installed, as specified on the System Requirements help page. The NI-DAQmx installer is on a DVD that comes with the NI hardware; it can also be downloaded from http://www.ni.com/drivers/.
• Verify the NI DAQ device is properly connected to the Windows computer.

If 'NILVSim.dll' is Missing: LabVIEW Control Design and Simulation Module Not Installed

If some subVIs or controls, like the 'NILVSim.dll' or the 'SimDog.xnode', cannot be loaded by LabVIEW when opening a VI in Windows, the LabVIEW Control Design and Simulation module is not installed.

To correct this issue:

• Ensure the NI LabVIEW Control Design and Simulation module is installed, as specified on the System Requirements help page.

If subVIs from '<vilib>:\Quanser\Rapid Control Prototyping Toolkit\' Cannot Be Loaded: Quanser RCP Toolkit Not Installed

If some subVIs with the following path <vilib>:\Quanser\Rapid Control Prototyping Toolkit\, like the CL HIL Write Analog (Scalar).vi or CL HIL Read.vi subVIs, cannot be loaded by LabVIEW when opening a VI in Windows, the Quanser Rapid Control Prototyping (RCP) toolkit is not installed. As an example, this issue is illustrated below.

To correct this issue:

• Ensure the Quanser Rapid Control Prototyping (RCP) toolkit is installed, as specified on the System Requirements help page.

If Getting 'VI Missing' Messages when Opening a VI

To correct this issue:

• Ensure NI LabVIEW and all the required add-ons, as listed in the System Requirements help page, have been installed.
• Ensure the Quanser Rapid Control Prototyping Toolkit has been installed on the Windows host machine.
