Epic Game Launcher, Unreal Engine - " Install Failed - The intsaller failed to intiliaze "

Hi guys, I’m still new here. So the
thing is I had to back up my Epic
Games Folder
, containing Unreal Engine 4.7.5 to a hard disk because
I had to System Restore my laptop
for unrelated purposes. After done
with System Restore I then copied the
folder from the hard disk to the Pc
Local Disk. When launching Epic
Games Launcher
, everything goes well
until I cannot find Unreal
Engine 4.7.5
in the Engine
Versions Section
. So I decided to
install the newest version by clicking
" Add versions", thinking it will only
update the previous version. Unreal
Engine 4.7.6
appears and whenever I
want to install it. This comes up

Anybody has an idea about this ? I am
trying to figure out myself but it
isn’t going so well. I’m trying to
make Epic Games Launcher to
recognize Unreal Engine 4.7.5 by
entering the configuration files and
adjusting them, so finally I could
update it to the 4.7.6. Can
someone please help ? It would be
really great. Note : I can launch
Unreal Editor ( Unreal Engine 4.7.5 ) by navigating through Epic Games
then 4.7 Folder then
Engine Folder then Binaries Folder then Wi64 Folder then
clicking UE4Editor. Can anyone
suggest some solutions ? Thank you
anyway ^_^.
