Hi Momo, so by default the object library stores its objects in a sub-folder inside MoI's main installation folder.

But also by default, as a security measure Windows prevents programs from modifying the contents of anything under Program Files. So probably that's what's happening to you.

Try running MoI with elevated privileges, to do that go to the shortcut you use to launch MoI and right-click it and choose "Properties". Then in there under the "Compatibility" section set the option for "Run this program as an administrator". Then when you launch it again it should hopefully work.
