Works good
Long could not normally remove Autodesk maya 2016 due to compatibility problems, installed this program, she did everything herself, and in a very short time. Therefore 10/10 !!!
It is good that this great tool exists, because then there are programs that resist being uninstalled. Congratulations.
I have tried but it doesn't work for me applying it to w7. Or is there another program to uninstall windows live.
