Did you modify config.lua?
If so, could you show me your user settings? (first 20 lines of config.lua)

"Xbde not supported, faking double buffer with pixmaps..." is a normal message,
but "lua error config lua:104:attempt to compare nil with number" is not. 
I don't have any Windows 7 machine to test with.

I get this same error, using Papercrop 0.43_rev19 on Windows 7 Professional 
64bit. I've tried two computers (each 64-bit Windows 7), and get the same error 
on both.

Could you try this and let me know the debug output?

    print("debug output", pageNo, rectNo, book_pages.nr_of_pages, nr_of_pages_per_pdf_book) 
    if (book_pages.nr_of_pages < nr_of_pages_per_pdf_book) then

(added one line on config.lua:103)
Thanks,

That's really strange. I will take a closer look at it next week.

Did you use the "process current page" button or "process all pages" button?
At the moment, "process current page" doesn't work with output_to_pdf option.
Thanks,

I had a similar error on Vista 64. Move the papercrop folder into your Program 
Files(x86) folder and it may work. It fixed my problem.

I installed paperCrop 0.45 rev61 on Win 7 Home Professional 64 bit, and I am 
seeing an error similar to the above.

Xdbe not supported, faking double buffer with pixmaps.
pFileName=main.lua
%.lua$ng presets/*.lua

everything is defaulted, no changes.

I tried moving everything to the Program Files(x86) directory, no difference.

I should have added, I am able to process changes, just get the above, but I am 
seeing a process blowup on a PDF I was testing with.

I figured out that if I use the Kindle3 as an output device, the blow-up above 
goes away.  I still get the Xdbe "error" though.

I think I fixed this issue. (Please ignore Xdbe error message that is unrelated 
to the problem.) If not, please let me know again using a new issue.
