Support Assist Plugin for Precision 7540

I recently purchased a 7540 laptop which came with Support Assist, Remediation and Plugin tools. I got a notification that an update was needed. Like many of you I was unable to update automatically. I then followed the instructions I found here - https://www.dell.com/community/SupportAssist-for-PCs/SupportAssist-update-not-installing/m-p/7396769#M89024

All went well until I followed the link to download a fresh copy of the Plugin. I entered my model number and was told that the plugin was incompatible with my system. Is there another place to download the right version or am I just hosed?
