ACR 1.0 for PS7

I just purchased a new notebook. I loaded PS7.0 and PSCS which ships with ACR 2.0. In the past I purchased ACR 1.0 for use with PS7 and would now like to load it to my new notebook so that I could use PS7.0 and ACR 1.0 or PSCS and ACR2.0. However, I need to download the patch to get PS 7 to PS 7.01 and I am confused since I cannot remember what I downloaded on my desktop when PS 7 was the latest version. I am looking at Adobe products downloads which refers to "Photoshop 7.9 Scripting plug-in v.1.0.2a". Is this the download I need on my notebook in order to install ACR 1.0 for use with PS 7?

I really like ACR 1.0 much better than ACR 2.0. It has more detail on the initial opening of a RAW file.

Thanks. Bev
