Sorry for not responding to this earlier; I don't think I received a notice that you had responded, and the monolithic workaround fixed our problem well enough. I will gather those files together for you next time I have a chance. I'm pretty slammed atm.

I came back to this thread because I have a couple users reporting a similar error (decompression #8) with our small, non-disk bootstrap installer. This installer contains five files and compresses to a 13.6MB exe, so it's definitely not a spanning issue in this case. I've told them to try re-downloading but I'm hoping you might have some insight into why this might happen.
