Downloading and Installing iScreensaver

Simple to try.

iScreensaver is always available for download from our website at http://iScreensaver.com. Once installed, all the screensaver functions are completely useable, even if the software has not yet been purchased or registered. However, screensavers created with unpaid and unregistered versions of iScreensaver are watermarked, as described above. Visit our store anytime to upgrade your license of iScreensaver and remove watermarks from your screensaver projects.

To install iScreensaver:

  1. Visit our download page at http://iscreensaver.com/downloads.shtml and choose your operating platform.
  2. Run the iScreensaver Installer; then follow the on-screen instructions.
  3. Read the (all-important) licensing agreements and select an install location. To give access to all users of the machine, save iScreensaver to your Applications folder. If you wish to restrict use to a single user, then save to a location within your User's folder.

Upgrading from iScreensaver Designer 3 or 4

There have been numerous file format changes since version 3, and even further changes since version 4.

If you open an older project in version 5, iScreensaver will transfer the old project to a new project file and add a version number to the new name. The new version will do its best to open and correctly arrange an older project, however make sure to re-visit each of your items and settings to verify their new status.

If you wish to continue to use your older projects for older platforms, we recommend that you do not save over them with the same name.

iScreensaver Designer 3 and 4 will require older hardware with their older operating systems than iScreensaver Designer 5.

Protocol:
The Authoring system versus The End User systems

The Authoring System: The computer on which you, as the author of a screensaver, design and assemble your screensaver using iScreensaver Designer.

The End User System: The computers used by your intended audience to view the screensavers you create.

The technical specifications for authoring systems are stronger than the technical specifications for the end users' system.

Differences within Platforms

Any direct comparison between the Macintosh and Windows versions of iScreensaver will reveal slight differences, including system fonts, text leading and kerning, captions, large icons, timing, and various versions of external plugins. Such variations are unavoidable in cross-platform software, however, we have made every attempt to minimize these differences and unify the user experience.

Using iScreensaver, you can design and assemble screensavers on Macintosh, and then run the resulting screensavers on Windows systems - and vice-versa. However, we encourage you to test the screensavers you design on as many actual machines as possible before distributing your screensaver to your end users. Variations are more than possible.

System Fonts

Your available font choices are dependent upon your authoring system's fonts. Non-standard system font settings and sizes are possible on the end user's machines.

Leading and Kerning

The system fonts display slightly differently on the different platforms. While we've attempted to approximate within iScreensaver, we recommend reviewing the final installers on each platform.

Captions

All text overlays will be converted to artwork during the build process, so what is seen on the authoring system is exactly what is seen on the end user's machine, no matter the platform. No fonts are included within the installers, and any fonts used within captions do not need to be present in your end user's machines.

Icons

You can import artwork as large as 512x512 pixels for use as icons, on Macintosh. However, Windows icons are limited to 256x256 pixels as their largest size with the self-extracting EXE installer limited to 48x48 pixels, and can only save 128x128 pixel sizes for its Mac Screensavers. iScreensaver will automatically size down your full artwork to the appropriate and largest size it can, on whichever platform authored.

Timing

Different memory, different processors, different hardware specifications, different software extensions - all these factors can slightly vary durations and timings both amongst similar computer models and between the differing platforms.

Please note that it is generally not possible to synchronize a video presentation closely with an audio track within iScreensaver. If audio+video syncing is important for your presentation, it is advisable to use third-party software (e.g. - Apple's Quicktime Pro, Final Cut Pro, or other third-party solution) to create a movie file with synced audio (although this may dramatically increase file sizes).

Be broad in your estimates, and forgiving in your timelines.

Compressed Installers

Both the finished Macintosh .zip file and the Windows .exe file, both created on either platform, are simple-to-decompress, single-file single-click steps for your end user.

External plugins

Inevitably, there could be some differences in multi-platform versions of Flash, QuickTime, or other third-party software, as well as with OpenGL video drivers. Those differences may be major, minor, or not problematic at all. Make sure to check with their websites for up-to-date information about their products.

Optimizing Performance

Many factors can interrupt a smooth flowing authoring system. Here are a few random guesses we can make and opinions we can offer.

Troubleshooting the Installation

There's usually nothing better for the installation blues than a complete system restart with a fresh download and reinstallation of the software.

See Appendix B: Troubleshooting, for more information and second-guessing.
