Shell Problems Shell Menus ShellExView Utility NirSoft Utilities
KuShellExtension64.dll - Explorer crashes when you right-click on a folder.

Not sure when this started happening in my Window 7 64bit. I had AllDup installed and intergration entries in my context menus working fine whenever I installed it on 22/04/28. Yesterday I discovered when I right click on Libraries or any item there-under, Doucment, Music, Pictures, Video, Explorer crashed with :-

"Microsoft Visual C++ Runtime Library

Runtime Error!

Program: C:Windowsexplorer.exe

This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information."

The same error happened when right clicking some Startmenu options.

Of course I used ShellExView to discover the offending context menu handler and noticed I do not have the AllDup entries on my menus any more even enabeling and disabeling from the AllDup application had no effect. So I had to disable "KuShellExtension64.dll" with ShellExView.

I have not triend updating the AllDup yet or updating Microsoft Visual C++ Runtime Library but being windows 7, not much will be happening.

Windows 7 version 6.1.7601
AllDup version 4.5.42

I guess if anybody is already using using your applications, they will figure this out themselves fairly quickly so I don't know what help this will offer other than the post maybe being searchable from the internet.
