That should not matter. I have the program on a different drive then my C drive where Python 2.5.x is installed. And it works fine for me where I have it.

I'm running Windows XP Pro.

It certainly matters where the ebook file is. If you don't specify a path it is going to look in the current directory. And since that was the current directory based on the prompt that is where the book needed to be. Of course, you can specify the path to the ebook file in the parameter.

When I kept running into all these problems I copied the books to the ..\scripts folder to make life a bit easier. I don't think that there was ever a problem with paths; I had to invoke the python exe program even though the .py scripts are clearly associated with it.

This is not something that I'm planning on doing very often, and now I know the workaround I can cope. I would agree that it is untidy and I'm not 100% happy with it but life's full of compromises and this is a really minor one.

Thank you again for all help.

+if verification == ver and cksum == temp_key_sum:

It can probably be made nicer but I guess you could keep two copies of the script.

So, in a case like this where it is a content encryption type, what PID do I use? I made the changes to the script, but it still requires that I enter a PID (e.g. python mobilededrm.py original.prc new.prc PID). I'm missing what I should enter for the PID.

Any valid PID. It's not used except in verifying its checksum.

I have had my Kindle for 24 hours and spent a good amount of time trying to use the Python kindlefix or mobidedrm scripts to remove DRM so I could use library books on my Kindle.

I have followed all of the script discussions, struggled understanding Python, continuously got syntax and ljust errors to the point where it waas pretty frustrating.

Just to try some other way to resolve this, I decided to use my XP based desktop, not my Vista based laptop. Of course, the kindlefix program worked immediately.

I am now able to read these library books on my kindle. The new issue is fixing some of the metadata that got corrupted in the conversion.

Yea, I realize my Mac directions probably went too far. It seems not all Macs have the folders I was using. I could make that easier too.

I got all fancy setting it up to put it in your path and such.

Oh well.

So I've been trying for a couple of hours now to get this script to work.
I'm using WinXP Professional.
The output I get in the cmd line is:

C:\Documents and Settings\Mryse\mp>python mobidedrm.py 9780316053952_9780316053
952.prc feedingyourdemons.prc XXXXXXXXXX
python: can't open file 'mobidedrm.py': [Errno 2] No such file or directory


I tried it without python at the start, but then I get no such cmd error.
I have Python 2.6.1 Installed.

what am i doing wrong?

Apparently the py file is not in your current directory.

It is. That's why I don't get it. I renamed it mobidedrm.py and it is associated with python.

[Marysart]

Nevermind! I did it! Thank you for responding.

[kevindorsey]

I found something similar to this, yes.

Similar to what?

When dealing with Windows, turn on the display of file extensions so you can see that your files are properly named. You could have something like filename.py.txt and you'd see filename.py and think it's fine. So having file extensions turned off for registered extensions is a really stupid default. It is your computer and you should be able to see what the files are named.

Yep, i noticed that, but renaming it did not work...I'm just not good in Windows. I had a mac before this and am now using Ubuntu.
Windows frustrates the hell out of me.
