The path you append to sys.path is not properly escaped:
>>> "E:\archive"
'E:\x07rchive' # \a has become the single character chr(7)
Use double backslashes or raw strings instead:
>>> "E:\\archive"
'E:\\archive'
>>> r"E:\archive"
'E:\\archive'
When you print it the extra backslash will be gone:
>>> print "E:\\archive" # \\ is the escape sequence for the backslash
E:\archive
