I have Used Labview 5.0 on Win 2K. Subsequently Upgraded to 6.1.
When you install It will Give you Message Wrong OS. You Continue the Install anyway. Secondly, to Make it Work - You will Need to Download Patches or Upgrades.
Depending What version you Have you May have to Go from 5.01 to 5.1 and then to 5.1.1. Also If you want to Have App Builder then First Install AppBuilder and then Update with Patches,so App Builder gets Updated too.
I believe you need Version 5.1.1 to Work in Win 2K.
And I think you may be able to Upgrade to it, by downloading.
And Yes I went From Labview 5.0 Base to 6.1 Full Dev System With App Builder For 1195/-.

Also you may need VISA or DAQ W2K Versions If you use any of them.
Good Luck!!
