Issue: An unexpected Error occurs when opening SharePoint Library Settings
Uninstall the Microsoft.SharePoint.ApplicationPages.dll from the GAC(Assembly) and then copy Microsoft.SharePoint.ApplicationPages.dll from Web Application’s_app_bin folder (C:\inetpub\wwwroot\wss\VirtualDirectories\222\_app_bin) to GAC(Assembly).
Note: You cannot interact with the GAC like a normal folder. Functions like copy, paste, and the normal right-click context menus will not display. Instead a special context menu is provided.
To uninstall from the GAC on Windows Server 2008 and newer, first open the GAC via Windows Explorer and type in %windir%\assembly. Then, select the dll in question, right-click, and choose Uninstall .
To install a dll, drag and drop the dll into this same Windows Explorer window.
