If you cannot find Bluestacks in the registry, it means the software has been installed without administrator access. To fix this problem, download a new package of Bluestacks from its official website, then right click the package and select Run as Administrator and confirm the operation. At the end of the installation, go to Start > Run > regedit and you will find Bluestacks in the following folder: HKEY_LOCAL_MACHINE\SOFTWARE\BlueStacks.
