If Chrome doesn't work for you in windows 7, try this:
Right click on your Google Chrome icon then select Properties. Under the shortcut tab you will see Target. The line ends with chrome.exe so just add --in-process-plugins after that.
So the line should look something like this:
C:\Users\user\AppData\Local\Google\Chrome\Application\chrome.exe --in-process-plugins
Then save change.
Now run Google Chrome and it should work fine on your Windows 7 64 Bit.
