I apologize. I feel like an idiot.
Apparently, I mis-entered something.
You guys are right the VLA doesn't keep track of whether the licenses have all been installed.
In partial defense of my having thought it did, Filemaker certainly intends to implement a system that will require you to "activate" your license. The "activation" will keep track of your computer's unique footprint as well as the license key employed.
Thank you. I would never have tried it again if you guys had not insisted I had to have entered something wrong.
