I don't know ... I've tried ScriptPro 2 several times now, but it only works on 32bit systems (and XP at that). I've tried everything I could think of, including starting it as Administrator, changing all the settings in W7 to allow all access to every file/folder without constantly poping up with that admin access dialog, changing username to be a full admin, only working with SCR & DWG files saved direct to a user-created folder on my C drive. Etc. etc. etc.
On 32bit XP it has no benefit over the old ScriptPro (i.e. it opens an acad session for each DWG in turn). On Win7 64bit I keep getting a situation of "Can't start the acad.exe process. Only in one case did it open the ACad logo screen, and then simply close it down without doing anything.
And I can't understand what you guys mean by: "It's fast". It needs to close and restart acad for every DWG you've added to the list. AutoScript doesn't need to do that since it runs inside of acad already - no need to start a new process, just open DWG, run SCR, close DWG ... next.
Anyhow, the very oldest LSP only thing I could find is this: http://www.jefferypsanders.com/autolisp_batchlisp.html
But that one sets SDI=1 in order to force acad to only have one DWG open at a time - i.e. it then works like the very old (early 90's) acads.
