http://askubuntu.com – When I try to install Ubuntu 11.10 using Wubi I get an error asking to check C:/users/home/appdata/local/temp/wubi-11.10-rev245.log I don't know what to do. I am not using the internet to install Ubuntu. I have Ubuntu in .iso format and I install it by keeping Wubi and the .iso file in the same folder. Here is the log file. (HowTos)
