Installing Kindle For PC on Ubuntu 10.10 Maverick Meerkat

I wanted to use Kindle For PC in Ubuntu 10.10 Maverick Meerkat using “Wine”, but got the below error while running install .exe

fixme:system:SetProcessDPIAware stub!

After some Google search, found that upgrading Wine to latest version “Wine 1.3″ will solve this problem.
Follow the steps given in this link to upgrade Wine to 1.3 – http://www.winehq.org/download/ubuntu
After that open Wine Configuration, and set Windows version to “Windows 98″ .
Now again run the Kindle installation exe to install and run Kindle without problems.
