Does your scope have the Windows XP SP3 installed? That's now 'abandonware', and available on the web.
You might also install the latest XP patches. Even though Microsoft stopped supporting XP quite a while ago, there are patches available if you make a registry change. Google 'Windows XP POSReady' for information. Even this is going away in April, so do it while you can.
I was asking about the Keysight Infiniium scope software the base operating system is up to date.
It turns out that you can not update directly from version 1.20 to 4.20. Please contact Keysight support to get the details
before starting the upgrade. Thanks TJB
