Downloading Pyscripter problem?

I keep trying to download Pyscripter on my 32bit Netbook, and I keep getting a range of errors such as "The installation package could not b开发者_Go百科e opened". Any clue on how to make pyscripter work?

Make sure your download is not corrupt:

>>> import hashlib
>>> f = open("PyScripter-v2.3.3-Setup.exe","rb")
>>> s = hashlib.sha1(f.read())
>>> f.close()
>>> s.hexdigest()
'dda9da0bb466c28db804c7989d14329c25cdcec8'
