Just click the 'Close' button when you see the pop-up to start Bluestacks.
You might see a notification saying that your graphics driver needs to be updated. The instructions are straightforward, similar to installing any other programme on your computer. Click on the download button for Windows on the left or Mac on the right. Here's how to get it running on your computer. Getting other solutions - such as the official Android SDK - to run, was more of a challenge, and in the end, we feel that Bluestacks is fast, reliable and easy to use, making it the only choice for most users. We tested several different ways to run Android apps on PCs, but only one app was able to perform reliably - Bluestacks.
You can now find Android in phones, tablets, hybrid devices, wearable devices such as watches, home appliances and soon the OS will be a part of cars too.
