A little more information maybe helpful. Are you saying you have upgraded from a OS to Windows XP and it caused problems with your application, or are you asking if there will be any problems if you upgrade? What OS were you upgrading from? LabVIEW 6.1 is the first issue of LabVIEW that was supported under Windows XP, so there should not be any issues there. In my experience, doing upgrades from one Windows version to another is never a smooth transition. If you are using any hardware I would advise that you uninstall the drivers and remove the hardware before the upgrade. I might go as far as removing existing National Instruments (such as LabVIEW) before you upgrade and then reinstall the software and hardware after you have upgraded. This will be the be
st way of ensureing you have as little problems as possible after you upgrade.
