First problem I encountered was while installing the Matlab.I tried to to start installation process but there was no response after license information widow.After changing Windows 7 background to classical theme I was able to install Matlab in Compatibility mode.But when I tried to run it I got full page of error information.After lot of brainstorming and web-research I found the easy way to install and use Matlab in Windows 7.
