Not from Europe (not sure about NK; cannot find any relevant EU sanctions) . Sanctions to Iran basically cover finance, transport and energy although if you had a "nuclear processing plant.vi", they might group that under "energy". LabVIEW is, apparently, also available in Iran, so I wouldn't be too quick to jump to conclusions about the OPs country of origin. Maybe it just cannot be bought online from wherever he resides.
