I tried to do a lot of research on this but couldn't solve the issue. I have tried installing android 6.0 r3, 7.1rc1, 6.0 r2 (64bits all of them) from this link http://www.android-x86.org/download. It a windows tablet which intel 64 based processor. Installation is successful, but touchscreen is not working. Only keyboard works. Anyone, can have some suggestions or answers? Sorry by the way, if this question is not according to the standard but I have come here after i couldn't really solve it.
