Because I had problems with Photo Gallery (difficulties to write a title, error 0x80070057 appeared) I uninstalled this soft but with the intention to reinstall. But this is now impossible !
I learned much later that Microsoft does not recommend deleting and reinstalling this application; I do not understand why. Trying a new installation errors always occur: see the attached file.
Other information: Windows 8, updated; firewall is on for Photo Gallery.
Thank you !
