I got four instances of errors being reported whilst decompressing .lzma files., but as it deletes them afterwards, its not possible to check whether they were completely unpacked or not without downloading the files again.

Yes, I'm working on allowing you to save the downloaded files, and I've thought about letting the installer give you the option of installing from the web or installing from the files stored on your hard drive already. Todo list very long.

No need to send me a log, you're the only person who has had this problem so far out of 20+ installs, so for now all I can suggest is that you check your internet connection.

Are you downloading from the code.google.com site, or from a local server? The downloader chokes on local sites for some reason, I'm looking into it now.

It subsequently fails the C:\camelbox\bin>perl5.10.0.exe -V test with: (snippage of error output)

I have not seen that one before. Usually if you're missing libraries of any kind, a dialog pops up telling you what .dll file was missing. This sounds like files got corrupted. Again, you're the only person who has had these issues so far.

I also posted a new release yesterday. You can try that if you wish.
