Most versions of Windows will allow you to open these compressed files automatically once you save them to your desktop. If you cannot, we recommend winrar as a good software option for unzipping compressed files. In the compressed folder you are about to download you will find an Excel spreadsheet containing the Perception Panel software, a readme file and a program which will allow you to play xvid video on a PC. You only need that if you want to look at perception panel videos (of which there are few) rather than just audio (of which there are many.)

You need to have Excel on your computer and an active Internet connection which Excel can access (some firewalls do not permit this.) You need to allow Active X, allow macros and disable macro security for the software to function. Some users have reported a "compile error in hidden module" error message referencing Sheet 11 of the spreadsheet. We believe this is caused by improper installation of Excel on some corporate networks. Please try a different machine if you get this error or contact your system administrator.
