I am publishing a book and every time I try to upload it to a pdf it says:
"Cannot save to file because it is in use by one or more background tasks. I have read a few other forums but I could not figure out how to fix mine. It is adobe Indesign cs6.
I need help asap, I am supposed to send to the printer Monday.
Windows > Utilities >Background Tasks will show you what task is using the file.
Exporting as PDF is itself a background task.
Try a reboot.
I did that and no background adobe tasks are running, and the ones that were I shut down.
I tried that a few times and it didn't work either.
