NIPALK error when initialising VISA

 

In running a test program 

viOpenDefaultRM(&defaultRM);

ViStatus stat = viOpen(defaultRM, "GPIB::1::INSTR", VI_NULL, VI_NULL, &instr);

I see in eventwvr

[nipalu] Warning: .\source\lib\windows\loadKern.cpp:145 - libKernelDriverInit: Could not load NIPALK. status=-50250

 

and viOpen returns VI_ERROR_LIBRARY_NFOUND

 

Clearly the library has been found (Loader Snaps doesn't show anything else) but the initialization is failing!

 

Can anyone point me at what might be wrong?

 

Alan
