Hello,
i am still having the problem described and i've tried all these listed possible solutions. i'm running vw12.5 with All additional modules (architect, landmark...). i'm on a mac 10.4.7 w/ plenty of ram and storage, logged in as admin.
i tried adding/removing the export batch from the workspaces, tried different workspaces, tried changing permissions, tried multiple files built in 12.5 and earlier versions. i have saved views.
they export fine as a single pdf, but when i try to batch, it flashes twice and nothing appears to happen.
as one guy recommened, i tried checking the /var folder and nothing i changed/tweaked seemed to effect the export working.
this has been very frustrating!!! i'm still looking for other possible solutions or workarounds
on a similar note, my Batch rendering is also failing. i have my dpi and pixel sizes down small (72dpt @ 1500px wide) and it will crash the program almost every other time i try to batch render.
the file renders fine on a coworker's computer only running the standard modules.
