Should be that when one upgrades to a new version of a product, one should know where the installer copy is. Where is mine? I upgraded, apparantly successfully to version 20.1.1.2 of NIS within the last 90 minutes but I cannot find the installer on my computer. This makes no sense. I upgraded through the version 18's "Check for Product Update" feature of the product itelf... according to webpage instruction,s clicked "Run" and "Run" in the two dialogs as they occured. One hour later, I had v20.1.1.2 successfully installed. One day I might like to take my copy of the installer for version 20, which I apparantly do not have (the installer), and install on some other machine, maybe on a new computer. What! Do I need to separately download the installer again?
