If you are now on Windows 8 or Windows 8.1 and was trying to install Bluestacks - Android Emulator for PC and have it crashed for some reason, here are some workaround to make the installation to work.
1. Update the graphic card driver
2. Or downgrade your graphic card driver - do this only if after upgrade your graphic card, the installer is still not working/running
3. Lastly, try to run Bluestacks installer with Administrator option by right clicking the application installer package, then select run as Administrator.
The third option finally worked on me and now I can play android games on my Win 8 PC.
