I am trying to install hyde on windows vista 64-bit. I am getting this error when attempting to run the generator:

I was looking to try out hyde as an alternative to jekyll, since I am in the process of learning python and django. But sadly can't get it running. Any help is appreciated, I will do a little googlin' and see if I come up with a fix. Thanks!

I am watching this issue because similar bug is occured at my Windows 8, Python 2.7.5.
And i encountered a similar error with Jekyll and also Hyde

UnicodeDecodeError: 'utf8' codec can't decode byte 0x89 in position 0: invalid start byte (HYDE)

Solved with removing Unicode BOM characters programmatically from my content files. Or manually
from http://stackoverflow.com/a/8898439/1766716

def removeBom(file):
    import os, sys, codecs
    BUFSIZE = 4096
    BOMLEN = len(codecs.BOM_UTF8)

    with open(file, "r+b") as fp:
        chunk = fp.read(BUFSIZE)
        if chunk.startswith(codecs.BOM_UTF8):
            i = 0
            chunk = chunk[BOMLEN:]
            while chunk:
                fp.seek(i)
                fp.write(chunk)
                i += len(chunk)
                fp.seek(BOMLEN, os.SEEK_CUR)
                chunk = fp.read(BUFSIZE)
            fp.seek(-BOMLEN, os.SEEK_CUR)
            fp.truncate()
    return 0

Encode Unicode files to -> Unicode Without BOM.

BUT, i encountered this error at the very beginning of the installation, in other words i have no content files and no content files with Unicode or with UTF without BOM.
