PCI-5112 grayed out in Select Device list for NI-SCOPE

[cnano]

Hello,

I've recently upgraded a system to windows XP. The latest NI device drivers are now installed. The PC's power supply was replaced as the 5V line had a low voltage. The computer and MAX seem to detect the PCI-5112 and PCI-5401 cards, but I cant seem to use them in the NI-SCOPE or NI-FGEN soft panels.

Launching NI-SCOPE brings up the select device list but the PCI-5112 is grayed out and cant be selected. Trying to launch NI-FGEN gives the message "All detected NI signal generators are in use by other processes."

Any suggestions?

Thanks,

Hi,

When a device is grayed out it means its resource is been use, in another application. Make sure you do not have any

application running on the back. If you still have the same issue let's follow the usual steps of doing a power cycle to

the entire system, chassis and computer. If this step does not help, let’s uninstall and install the NI-SCOPE drivers.

I hope it helps

I am having a similar issue with my PXI-5114 digitizer.

The good:
The device is recognized in MAX as "Dev2" under the NI-DAQmx Devices
The Self-Test passes
Using the MAX Test Panel, I can see signals on the panel, so that works well

The bad:
When I open NI-SCOPE, the 'Select Device' screen shows 'PXI-5114 at Dev2', but it is greyed out.
When I select 'Simulate' I get the error:
"Autosetup Failed! Property Node (arg 1) in sfpScpCap_UtilityCapabilities.vi->sfpScpCap_Create.vi->sfpScpGlb Create.vi->sfpScope Front Panel 1.vi"
 When I press OK, I get a second dialog:
"Initialization Error! Ensure that your scope device is properly installed and is not in use by another process, then try again. If you have not run MAX since installing your device, do so now. Error : -1074130426. The registry entry for the master configuration store does not exist or the file could not be found."

Also, when I run the LabVIEW example 'niScope EX Getting Started.vi', I can select Dev2, but when I hit the run button, I get the following error:
Error -1074130426 occurred at niScope Initialize.vi. Possible reason(s): The registry entry for the master configuration store does not exist or the file could not be found. IviConfigServer.IviConfigStore.1:get_MasterLocation failed. The registry key for the master configuration store does not exist or the file can not be found.

The ugly:

I've rebooted numerous times.

I've uninstalled and reinstalled NI-SCOPE and thus the drivers for the device.

I've updated to the latest version of NI-DAQmx.

This is a new system and I've recently installed LabView Developers Suite for the first time (before I connected the hardware).

It seems like it could be a couple of things:

1) Something else has the resource blocked, but I can't figure out what it would be and why it would work in MAX and not elsewhere.

2) Issue with this master configuration store, but I can't find any information on what this is or how to fix it.

Any help would be greatly appreciated.

Hi Alex,

It sounds like there is either a missing or corrupt registry key that is associated with the IVI driver that installs with NI-Scope. If you go to "run>>regedit" do you have anything at  HKEY_LOCAL_MACHINE\SOFTWARE\IVI\ConfigurationServer? 

Whether you do or not, I would suggest un-installing the NI-Scope and IVI drivers and then re-installing. They point, is that the IVI driver will get re-installed and hopefull replace this missing registry key.

With many thanks, I've solved this issue. The short of it is that it seems to be a perfect storm from Windows. Basically, the IVI Configuration Server was never installed correctly or was corrupted because of an issue with msxml4.dll that was recently updated by Windows Update.

The long of it is that my registry you suggested I look at is:

(Default)    REG_SZ   (value not set)
MasterStore   REG_SZ   C:\documents and settings\all users\application data\ivi foundation\ivi\iviconfigurationstore.xml

Of course, when I go to this directory, there is not even the IVI folder, let alone the .xml file. I search my hard drive and couldn't find the file. When I went to MAX, I had found an information tab I didn't notice before that stated an error:
"The provider was unable instantiate the IVI Configuration Server"
Searching for this, I found a link for the IVI Configuration Server Error in the KB
http://digital.ni.com/public.nsf/allkb/4B4D667C9F2C502586257559000CAB42

and they suggested to reinstall the IVI Shared Components. When I did this, I received and error during the installation about an issue with msxml4.dll. Fortunately, I had saved a previous version of this file before the issues I had with the Windows Update. I went back to the previous file and continued the installation. It finished successfully and NI-SCOPE now works!

Thank you so much for the help and for pointing me in the right direction. What a relief.
