DOWNLOAD SOFTWARE
Register

All of our software is available to download for Mac and Windows platforms. Many of the titles are FREE and can be used without registration, however purchased digital downloads of our software and full-screen versions of individual applications require a registration key to run beyond a 30-day demo period. Use the BUY links to visit our ONLINE STORE to purchase.

DIGITAL DOWNLOADS

After purchasing an installer download through our online store, you will receive your registration key(s) and download instructions via email. You can download the software installers at any time using the links below.

FULL-SCREEN DOWNLOADS

Most of our software titles are available in full-screen versions that black out the remainder of the display window, preventing access to the desktop and any OS menus or toolbars. If you have purchased an installer download or DVD copy of any of our software and wish to obtain the full-screen version of an application, download the required files using the links below and then contact sales@spaceupdate.com to request a registration key to unlock the full-screen application. If you have already paid for the current version of the software title, then there is no charge for unlocking the full-screen version.


All apps are available for Mac OS X (10.7-10.14) and Windows (7, 8, 10, 11).

NOTE: Software support for MacOS ends with MacOS 10.14 "Mojave"

MacOS 10.15+ users should contact support@spaceupdate.com for info on 64bit versions of our software.

SECURITY WARNING: : MacOS and WinOS warn against installing applications from "unknown developers".
