I have spent almost 72 hours looking for the best solution to play clash of clans on windows 8.1 PC.
Below are the working files that enable me to play clash of clans on my newly upgraded 8.1 laptop.
Bluestacks Offline Installer from aTechguide
BS Multi Tool thanks to codelover from http://forum.xda-developers.com
1-Install Bluestacks
2- Extract all for BS Multi Tool inside the Bluestack folder
C:\Program Filex(x86)\BlueStacks
3- Copy SuperUser into the BS Multi Tool folder and do not extract the file
C:\Program Files(x86)\BlueStacks\BSMultiTool
4- Execute BS Multi Tool
5- Choose 1 Auto Rooter/Unlocker
You can link your devices but you need to sign in first. I am not taking credits for all the works and efforts taken by the greatest coder codelover and BlueStacks team and not forgetting the aTechguide.
This is a reference point for myself to run CoC on my laptop in case it turned blue again.
Enjoy your CoC running on PC.
