How to completely uninstall Andy and get rid of all files from computer ?

I am facing some trouble and uninstall seems not to work for Andy. I am advised to reinstall Andy emulator but on reinstall it again not working. I think its due to that its not completely uninstalled because of uninstall, I still see lots of Andy files here and there. What is the proper way to get rid of all those files created by Andy on my PC and make it clean as if Andy was never install. This way I can try fresh install of Andy to check if my old install had problem or actually computer have problem or its in Andy itself .

Rachit, you are absolutely correct that when you try to uninstall Andy, it is not completely uninstalled. If you think completely removing Andy can fix your system then you have to manually find some folders and remove them.

Please find and delete following folders completely :

C:\Program Files\Andy
C:\Program Files\AndyOfflineInstaller
C:\Program Files\AndyOfflineInstaller42
C:\Program Files\AndyOfflineInstaller43
C:\Users\<user>\Andy
C:\Users\<user>\Virtualbox VMs\Andy

Run following for assurence as you have already tried uninstall ..
C:\ProgramData\Andy\AndyUninstall.exe

Finally remove this folder too.
C:\ProgramData\Andy

If you also want to remove Virtualbox which comes with Andy and Andy use it for virtualization, you can uninstall it from Control Panel>Programs and Features.

Restart your computer and you are done. Now you may go ahead and try fresh install to see your problem resolved.
