step 2 is rather crucial. The screen looks complete at this point the quick support download is below the fold.

Nice. I see Products and Download Remote Assistant but Quick Support CLient isn't evident anywhere that I can see. No "Download page" or at least it isn't obvious otherwise I would have found it. The site has probably been changed since you were familiar with it. Give me a URL if you really want to help.

Not this I assume
Home > Products > MSP360™ Remote Assistant > Download
Download MSP360™ Remote Assistant
nor here...
https://www.msp360.com/company/media/downloads.aspx

But...
"Quick Support Client
Optimized for instant support, the compact no-installation package will be available to allow you establish the connection." "...will be available..." When and where?
