Explorer Shell Extension

The shell extension adds Beyond Compare to the Windows Explorer's right-click menu.  Then, from any Explorer window, you can select the files or folders and launch Beyond Compare to compare them.

Installing the Shell Extension

During installation, check the box labelled "Include in Explorer context menu".

To enable the shell extension after installation:

  2. In the Explorer Integration group, enable the Include Beyond Compare in Explorer context menu option.

The Include Beyond Compare in Explorer context menu check box isn't available if you selected Create portable install when you installed Beyond Compare.  To enable it, install Beyond Compare again and select Install for all users or Install for current user.

It may require a reboot for the shell extension to show up.

Shell Extension Problems

If Beyond Compare's shell extension is not working, other shell extensions installed on your system might be causing a conflict.

You can use the handy freeware utility ShellExView to disable shell extensions until you determine which one is causing the problem.

Microsoft Application Virtualization

Microsoft Application Virtualization does not support shell extensions.  This prevents the use of Beyond Compare's right-click menu in Windows Explorer.  See Microsoft Technet for more details.
