Hello morrison,
Current versions of LabWindows/CVI for Windows build 32-bit Windows applications intended for use on Windows 95, 98, Me, NT, or 2000 running on x86 processors. From what I have heard of NT Embedded, it is supposed to run "off-the-shelf hardware and software". Thus, I would suspect that CVI applications would run on NT Embedded. However we have not tested LabWindows/CVI with NT Embedded, so we cannot make any guarantees.
