Thank you brummyfan for your helps ;)
ETDWare is not in my program list! when i try to install it i got failed
I did also run sfc /scannow command 3 time and every time it said found cropped file and fixed them!
I didn't try DISM command yet but i'm sure problem is ETD ! its installed but there is no sign of it and i cannot...
thank you for your quick replay!!
i did what you said;
uninstalled Launch Manager from control panel and download it from that link you send and installed again! (but i think nothing happened there!)
then download synaptics driver from that link you send and install it! it successfully...
hi everyone
a few days ago, i did a stupid thing ! :|
the Synaptics touchpad driver was installed on my laptop (Acer-E1 572G - Win 8.1 - 64bit) and i installed Elantech touchpad driver without uninstalling last one!!!! :|
so, touchpad and keyboard stop working any more!
i did uninstall Synaptics...
