I would like to know if Vi-Cell XR v2.03 Viability Analyzer is compatible with Windows 10.
There is nothing mentioned about the version you have specified above. I've accessed their official website and looked through the pages to find compatibility and system requirements, but there is nothing available.
I recommend you reach technical support to get in touch with the technicians and they should provide all the necessary information related to this inquiry since nothing public is available: http://www.beckman.com/particle/service-and-support/met-one-and-hiac-applications
