I doubt that this is a Windows problem; there are several reasons why an ActiveX control could turn to evaluation mode (see KB link below). I would suggest that you uninstall the OCX controls from your new computer and instead run the ComponentWorks installer for proper installation/registration.
If you have version 3.x or later of the CW controls, you could also run the Measurement Studio License Fixer Utility found in the following Knowledgebase article:
http://digital.ni.com/public.nsf/websearch/86256A47004E16D186256A99007BEFB7?OpenDocument
This utility will help you diagnose the license state of your controls and will try to fix any broken licenses. Please read the KB carefully as it may not apply to your particular setup.
If none of the solutions off
ered here works for you, please email us through http://www.ni.com/ask so we can assist you in a more direct way.
