i have a new computer. i'm using the same iconfig folders as always. when i go to IGO or IGB i am getting the following error: Error opening file for write (1) File: C:\WINDOWS\system32\isogen.log. when i go to that file it is telling me it is not there. anyone know what could be happening here?

The fix for this is to make sure the Start In under Options is not left blank. c:\cadworx 2018\ and it all works. I should have looked at this prior to posting. Sorry.

The log file gets written to the folder were the drawing is saved. I have this error on pc's with incorrect permissions and usually when running an iso from a drawing that has not yet been saved.
