Photon Engineering makes developmental test versions of the FRED Optical Engineering Software available to users on an occasional basis. Users under a current annual support contract can have early access to the newest features and the latest bug fixes. In return, we ask for your feedback regarding the new feature implementations and any potential bugs.
As with any software product under development, please be aware of the following:
It is important to consider the issue of FRED file version compatibility. FRED model files are fully backward compatible, but they are not forward compatible. For example, FRED files created with earlier versions can be read by FRED version 25.50.0, but files created by version 25.50.0 can not be read by prior releases.
This development version release falls under Photon Engineering’s FRED End User License Agreement section 4,” Limited Warranty”.
Before downloading you should verify that your current software authorization codes will allow you to run the development version. To do this, launch your current version of FRED and go to Menu > Help > License Authorization. If the version limit reported in the License Authorization dialog matches or exceeds the development version number you want to download, then you will be able to run the development version.
Note: You may observe that after downloading and running the FRED installer, Windows presents the following dialog. If you see this warning:
If your version shows an option to display “More info”, please click on that link. You will then be presented with an option to run the installer file.
If your version of this dialog does not show an option to display “More info”, please take the following steps:
Right mouse click on the FRED installation executable and choose “Properties”.
On the General tab of the resulting dialog, look for an option in the lower right that says “Unblock”. Toggle this option.
Close the properties dialog and then run the FRED installer executable again.
Release Notes are included with your FRED installation and can be found by navigating to Help > Release Notes from the menu.
