Microsoft has made it extremely difficult to recover edition info (Enterprise, Express etc.). There are only a few ways to do it, which are described
here. These methods cannot be replicated by Lansweeper and hence Lansweeper cannot scan edition info.
When it comes to version numbers: if no version was retrieved during software scanning, you could possibly do a custom file scan of an executable. However, it might be difficult to find one that is present in the same location on all machines.
