What error are you getting when you try and install?
I have the same problem , I cannot install adobe flash for ie 10 / w 7 / 64 bit !
upon trying to install flash , I am informed that I have to close ie 10 in order for the program to install !
ie 10 is closed , yet the error still appears ! trying to uninstall the same program , it says the same , close ie 10 !
