The following are updates to Magic Mouse products. These updates are complete executable programs, and are not patches. Once you download and unstuff or unzip the updated program file, you will need to trash your old program file, so that it is not run by mistake.
NOTE: If you are a Discus 2 user, you cannot simply download the version 3 program file. Or if you have version 3 you can't simply download the version 4 rogram file. In order to run Discus you must have the matching art file from a Discus 4 DVD or full download. The posted version 4 update will not work with prerelease versions, this version 4 program posted here is only to update the older version shipped on your DVD. If you need to order an upgrade please visit our Online Store.
NOTE: These updates are only for the full retail versions. If you are a user of Discus LE, Discus RE, Discus EP or any other special limited version of Discus bundled with a CD Printer or burning software, these updates will not function. We have prepared a chart showing the difference between the Discus RE and full Discus product. Please visit the website of the company that bundled your software such as Roxio for updates to your software. Special upgrade pricing is available at our Online Store to convert these limited versions into the full Discus product.
If you request a download of an archive file, and the download shows as gibberish, then perhaps it is time to get firefox from mozilla.com, because both Safari and IE on the macintosh are poorly maintained products.
