Hello NetSim,
I would recommend trying a newer version of the CVI Run-Time Engine available from "http://www.ni.com/download". Click Drivers and Updates >>
Current Software Versions >> LabWindows/CVI Run-Time Engine. We have done our best to keep the newer releases of the run-time engine backwards compatible with older CVI releases. However, I would also recommend reading all of the Release Notes for the newer versions of CVI to understand what has changed and if it will affect your program. Please see "http://www.ni.com/manuals/" >> All Manuals (Current and Previous Revisions) Sorted by Product Line >> LabWindows/CVI Products.
