we are using an old Windows XP PC with "EZChrome Elite" for operating a VWR "LaChrom Elite" HPLC.
I recently changed something on the Computer by trying to install a network printer and thereby somehow activating the Windows XP homegroup. When I wanted to open the instruments in the EZChrome software, it told me "Unable to open the instrument because there are no licences available. Please contact the system administrator."
Now I found the "Key" software that is a part of EZChrome, that manages licences. The Problem is, that this software is using a licence file (which I have), then a serial number, which I also have and typed in. Then it gives out a "request code" that I then can send to Agilent and they send back the "enable code". The Problem is with our old licence file, now a new request code is generated and thus the old "enable code" that I got doesn't work. The software is not anymore supported, so I cannot get a new enable code my agilent.
Is there anything that can be done to get the old "request code" back, so my old "enable code" would fit again? I know it is quite desperate, but I am a little frustrated that I cannot use this machine because of the "enable code".
Also, I don't even know the (still supported) alternatives for this software and my old HPLC.
Any advice is highly appreciated
