There is no real installation for NetscDDE because XFolder comes preconfigured to let you use it. The default configuration adds a "Netscape DDE" item to all folder context menus which displays the contents of that folder in Netscape.

However, there are a few extra things you can do with NetscDDE.

1. Create a program object for the `NETSCDDE.EXE` file in the `/BIN` subdirectory of the XFolder installation directory. Associate this program object with `*.HTM` and `*.HTML` files, and you can then double-click on HTML files on your hard disk and have NetscDDE open them.

2. You can also specify NetscDDE as your default browser in the OS/2 Warp 4 URL objects.
