I am trying to export a set of images to PDF. The function runs and then brings up an error message that the file is not available for writing
Like I said, the file doesn't have to be open. Was the file with the same filename you were creating the PDF as already existing in your system? If it was, even if you had opened it in Finder and selected the file for Preview in Finder, PDF writing will fail sometimes.
Either that, or, a permission issue. Can you try creating on a different location or check folder permissions to ensure you have permissions to write to that file? Or, can you try with a different filename in the same or a different location?
No files with the same name exist. I've tried different folders and file names but it still comes back with the message "Unable to open file for writing. It may be locked or unavailable."
This would tend to suggest that it cannot create the PDF file. Could this be an external problem with PDFs
Since I only need it occasionally I'll do it via a windows system since that works flawlessly.
Can you export the files as JPG images first.
Then open Photoshop > File > Automate > PDF Presentation
Add your jpg images here. Create a Multi-page document and hit OK.
See if this is able to create the PDF for you. If it works, there is no problem with the PDFwriter extension in PS. It will have to do with some file permission or something else which we have to dig deeper to analyse.
Did you try the PDF Presentation option I suggested?
Does it still not work?
Did you try clearing prefs? http://forums.adobe.com/thread/375776
Not that I'm aware of. But, you can try using CS Cleaner tool to clean traces of CS installations and re-install the program afresh. This will fix faulty installations.
