Hello Raybie
Are you able to launch calc.exe via the command line without using CVI? Which version of CVI are you using and on which OS. I tried this with CVI 7.0 and XP and calc seems to work fine. Make sure you have updated your OS to the newest service packs as well.
Let me know what you find.
Thanks
