Delays to Orders

Windows 10

Our experience is that our Windows simulations work as expected on all past and current versions of Windows, including Windows 10.
If you have a problem related to Windows, particularly Windows 10, please first check our Windows Problems page.
If you need help, please contact Support.

Read Me First page

We have brought together on a single new page all the information about running our older non-Windows simulations with any version of Windows from XP onwards. Unless you are running a very old PC, please check there first before ordering any non-Windows simulation. This page now has a link to instructions for setting up DFend-Reloaded.

Place an Order using our online order form

We strongly recommend use of our online order form, and downloading your order will also eliminate postal delays, particularly for overseas customers. You can now specify delivery on CD or by download, or (for non-Windows programs only) on floppy disk if you can’t accept a CD; we can’t guarantee that floppy disks will continue to be available. The default is now that we send you an email containing a link from which a zip file can be downloaded. To order click here.
