Trying to install the new Foxboro update, and I have had my system packed away since the original Everette update so I'm thinking I may have missed some things there.  But in any event, installing many of the sub-products under the SONAR Platinum hive within the Command Center yields the following error:

"The setup files are corrupted. Please obtain a new copy of the program."
 
Am I screwed here?  I tried to "rollback" to the Everette Update 1 level of the main program, but that didn't help at all.  Is there a fix for this somehow, or do I need to uninstall everything and start over?  Man, that would suck lol...
 

In CCC settings, click the gear in the upper right to see where CCC is downloading the files too. All you need to do it navigate to that folder with Windows Explorer delete that specific file. If CCC sees a file there, it will try to use it, but if it flags it as corrupted you need to manually remove it so that CCC will download it a second time.
 
Do not uninstall or redownload everything, simply remove/delete the files from that directory which CCC flags as corrupted and run CCC again.

I had 2 files that I downloaded in CCC that were corrupted.
I just went back in CCC and downloaded them again.
I think it was because the download server was maxed out with everyone downloading the files at the same time.

To try this, I deleted the CCC file in "C:\ProgramData\Cakewalk\Command Center\Downloads" for Local Help & Documentation and got a different error saying Command Center had run into trouble downloading the files.  Retrying....

Strangely, even when the indicator from CCC is failure of some sort, very often the indication upon it reloading is a green light on the item.

The green light says you downloaded the file. Just reinstall.
 

The CCC is supposed to do the checksum to verify a good download.

mettelus fist bump bro. Your suggestion fixed it.
