From the official Agilent compatibility matrix:
B.01 =NT4 Sl4
B.02=NT4 Sp6a
C.00=NT4 Sp6a
D.00= 2000 Sp2
D.01= 2000 Sp3, Sp4 XP Sp1a
D.02=2000 Sp3, Sp4 XP Sp1a XP Sp2
D.03-E.02= XP Sp2
E.02 sp1=XPSp2, XP Sp3
E.02 sp2= Vista, Vista Sp1
E.02.01 and above = Vista Sp2 through Windows 7
5972 is supported through C.00.01
5890 is supported through B.02
If using a 5972 with C.00 you must be using a 6890GC
I do know that any software that says up to XP Sp2 will refuse to install if you have Sp3, we tried it and the installer warns you have Sp3 and aborts.
I also once did an install of C.00 on Windows 2000 and it will run but the install program will not generate the icons on the desktop or in the start menu for you to start the program, I had to copy a shortcut from an install on an NT system to my W2K system and with all the paths being the same that worked.
Though Version B looks rather dated it is one of the best in my opinion. Version C was not really any different except for what it supported(adding support for the 5973). A quirky thing about versions C and earlier, even into the W3.11 versions is they will read data files from the LC Chemstation and you can use the RTE integrator and the QEdit functions on those files, but from Version D on they will not read the LC files. We keep an NT version running to quantitate and generate the built in QC forms on our LC data.
Version D originally dropped support for the HPIB interface but later added it back in for users who had older 5973 models, but it was gone again by version E I believe.
We also just completed upgrading all of our MSDs to the E.02.02 so that we have compatibility with W7, we had too many computers on their last legs to risk losing an instrument from the death of a computer. One warning when doing this, the newer computers can be too fast for the JetDirect interfaces on the instruments and you may have to upgrade those also if you have a 5973/6890 equipped with those.
I hope that helps, and if you search you can find the compatibility matrix in an Excel file on the Agilent website under the support section. It should still be posted there.
