Hello Eran,
This error could be caused by having insufficient privileges to the IVI directory on your system and can be resolved by logging in as the administrator or having access to of all National Instruments files.
If this is your case, the following KnowledgeBase 3JL6JQSF explains how to solve your problem. If that doesn't work, this Discussion Forum post describes the same error and has some suggestions on how to fix the problem.
If this doesn’t help, here are some questions/suggestions:
1) Are you running an example program?, If so, which one?
2) The necessary drivers for your board are: NI-DAQ, NI-VISA, IVI-Engine, and NI-SCOPE. What version of those drivers do you have? If you are missing any of them, you can download the latest versions under NI Drivers and Updates.
3) Are you log onto your computer as the administrator?
4) Try running a simple example called "niScope EX Getting Started.vi" located in LabVIEW under Help>>Find Examples and then browsing to Hardware Input and Output>>Modular Instruments>>NI-SCOPE>>General. Does the same error occur at niScope Initialize?
Let me know how it goes. Good luck,
