Going to bed. will check back in the morning.

Thanks everyone. I was finally able to repro on a fresh install of Win10 using the info that reginald Stjohn sent.
 
This is a temp fix until we can fix it for real, it looks like the core issue has to do with the version of IE that is embedded in Windows is no longer playing nice with the a recent Win10 update. This version just cancels the navigation event until we can sort it out.
 
If you're experiencing a crash in C3 when downloading/installing files please try this version: http://static.cakewalk.com.s3.amazonaws.com/command-center/CakewalkCommandCenterSetup_1.1.2.4.exe
 
 

1.1.2.4 seems to be working.
 
Why are you guys using IE? 

Willy, it's awesome you and your team are available and are pushing updates. Thanks for the great support.

1.1.2.4 seems to be working.
 

 
Great glad to hear it.
 

Why are you guys using IE? 

Because its guaranteed to be present on every Windows system and doesn't require any additional dependencies. We'll probably be re-considering that now. It would make the installer a bit bigger - but CEF might be our next stop.

CEF would be better. I am still wondering why an embedded browser is even necessary. HTTPClient and forms/xaml should be enough for what you all are doing. 
 
Anyway, happy to help out if I can. Thanks again.

Thank You Willy.
1.1.2.4 did the trick and everything is back to normal again.
You guys deserve a standing ovation for your exceptional support.

I too am having the problem Toit described. I am running Win10 Home on a new computer. I get an error when trying to install Sonar Platinum saying that CC stopped working, and Win needed to close it. I sure hope someone will find a solution to this and share it with us!
Edit: I tried the CC link in the post above, and that didn't seem to fix the problem.

Hey,
have you checked to see if any of your packages have downloaded and are now ready to install?
I had stops as well but then I checked and many packages where ready to install...
