Error Code 16:

Patch ONLY for Version 5 DVDs for Mac users upgrading to Yosemite OSX10.10

Since our Wordshark and Numbershark  5 DVDs were produced, Apple have further upgraded and altered their operating system. As a result, customers upgrading to or running OSX 10.10 “Yosemite” will experience an “Error Code 16” when attempting to install or run either program.


We have produced a fix for this issue for both programs, available as free downloads: Please click to download the patch for your program, and read the instructions below whilst the file downloads. This normally takes between 5 minutes and 2 hours, depending on your broadband connection speed.
