I run into problem when tried to install Ubuntu 11.04 on Windows 7 using wubi installer . It downloads the image for sometime and ends up with the error that says

Permission denied: for more details see the log file

In the log it seems to be like DownloadError: Problem connecting to tracker - urlopen error (10060, 'Operation timed out')

but my network is good and I checked it.

Tried using wubi several times, but ends up with same problem.
