Download instructions for RSLogix 500

I tried to follow the tutorial video to download RSLogix 500 on my system " How to Get Started in PLC Programming in RSLogix 500 w/ Free Software Downloads". However, I get the following error message seen below:

“The selected product/version is retired and its downloads are no longer available from the Product Compatibility and Download Center website (PCDC). We recommend upgrading to the latest version of this product if compatible with your current system.”

There is an option to request unlock, but it says it will only be unlocked for the duration of my session. Does this mean the download is not available for free anymore?
