Hi,We are running our Delta Plus on Windows XP using Isodat 2.0 with Service Pack 1.21. Last week our Dell computer went down and although we can revive it, we realize it is only a matter of time before it really dies forever.I wanted to know if anyone has had any luck running their instruments on a newer operating systems. If so, what are you using? What steps did you have to take to get everything to communicate? Has anyone tried running XP through something like VirtualBox or Microsoft Virtual PC or something similar.Thanks in advance for your advice,Jen WalkerW.M.
