Asset Managment 7.5 SP1

Hello I am trying to restrict the use of the collection editor on my
client machines as I work in a school district with over 10,000 students.
It would not be wise to let our "little angels" adjust my inventory. I
know I can set the editor to never but the problem being is that my techs
can no longer run the editor. Even if i use the scannow:edit the editor
will not run. I get the error "Cannot open the selected inventory!". Is
there any way around this? The only thing I can think of is to come in at
night and do scans which I am not about to do. Thanks in advance!
