[SOLVED] .azw4 to .pdf

Hi there!

I am trying to convert a non-DRM .azw4 file to .pdf. I did it before using mobiunpack.py, but I can't remember what I did last time and everything I've done so far hasn't worked.

So far, I've tried converting the .azw4 to .mobi in calibre. Then, I use mobiunpack on the file. Unfortunately, the .pdf comes out poorly, with no formatting or pictures. I think this might be a problem with the .mobi file itself and I'm not sure how to fix it.

I have also tried converting the non-DRM .azw4 directly in the mobiunpack.py script, but any time I specify the .azw4 as the input file, mobiunpack.py immediately crashes.

Does anyone know what I might be doing wrong? I've done it correctly before, so I'm not sure why it's not working this time.

I'm using ActiveState ActivePython 2.7 (32-bit). I am running on Windows 7. I have tried both mobiunpack v47 and mobiunpack v50. Any help would be greatly appreciated.

EDIT: THis is the error message when mobiunpack crashes:

It must be a problem with that particular AZW4 file (or your python installation), because I have no difficulties extracting the PDFs from AZW files using the latest mobi_unpack (v.50). It's interesting that it appears to be the console-less pythonw interpreter that's actually doing the crashing. Have you tried bypassing the GUI front-end for mobiunpack and just running it from the command prompt? That would take pythonw.exe out of the equation.

Also, you could try the third-party calibre plugin version of MobiUnpack. It will allow you to extract the PDF from the AZW4 file (with no conversion involved). You can use calibre's built-in "Get new plugins" functionality to automatically install the plugin.

I added the plug-in and it worked perfectly! Thank you so much!

wow, that worked perfectly for me and it was literally instant as soon as I used the toolbar. Every single bookmark is there as well. I knew after trying a dozen times with Calibre's conversion that there had to be a better way. Awesome work sir, thank you.
