Failed to convert large book

[HarryT]

I've recently bought the "Delphi Complete Works of Jules Verne", which is a large book (48MB Mobi file). When I try to convert it to ePub format using Calibre 2.2 I get the following:

Is is just too big for Calibre to convert, or are there any settings I could change that might allow it to work?

Thanks!

Use a 64bit version of calibre on machine with lots of RAM.

Thank you - that's what I thought would be the case .

In the end I solved the problem by buying the ePub versions from Delphi. Cheap enough not to notice .
