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.

Wubi is trying to download the desktop CD ISO for the install using a bittorrent client. It requires that pyrun.exe (the python runtime that Wubi uses) be given permission to your windows firewall. If you granted pyrun.exe firewall access (there would have been a popup asking permission) then you may be blocked by an upstream firewall e.g. some colleges/universities block bittorrents.

If that's the case you should download the desktop CD iso yourself from http://www.ubuntu.com/download/ubuntu/download and save it in the same directory as wubi.exe before running (and Wubi will find it and use it).

It worked for my by downloading the image and placing it in the same folder where the wubi.exe sits in. And one should not forget to disable network before executing this. It works smooth.

I don't know which one will work, lets try several solution:

1. run wubi.exe with right click [rus as administrator]
2. Try to install ubuntu on another drive [if run as admin does not work][expect C]
3. If you will get any disk error during wubi installation then just click continue several times. Surprisingly it works.
