Hi, world.

I had installed MS Home and Student and Photo Gallery worked fine. Then I tried to upgrade it and Windows seems to have  downloaded the essentials photogallery version. Now phto gallery does not open anymore: error code )x8007007e, wlid.dll file missing, WLXPhotolibrary Main dll. To remedy this, can I install my original MSHome disk again, without loosing any files? Or is there another way. I rely on the photo gallery and it's editing functions.
