AUSST Updates for Adobe Acrobat Pro

I suppose updates for Adobe Acrobat Pro thru AUSST can be deployed using RUM tool on client side. if I recall correctly, it did work in our environment last year, but now it just says no updates found, even though new updates are downloaded and available for Acrobat Pro on our AUSST server.

Also, if this does not work, how can we exclude the Acrobat updates to be downloaded everytime we run the update script with AdobeUpdateServerSetupTool.exe ?

Thanks!
