The DLL/OCX issue is the fifth item in the Knowledge Base, might want to check it out.

This link has info that might help (it did for someone else who had this error).  Also, in a prior post from Noel for an old thread for the same error, he indicated that the service that is failing is a Windows service they call to register components and that all pending Windows Updates must be completed and then Sonar can be installed.
 
That thread had this link in it as well:

Here is a link to obtain the Microsoft universal C run time update - it has links to get the appropriate package to download for whichever version of Windows you are running:

Thanks Anderton, the knowledge base was the first place I looked for a solution.  Nothing there helped.  And thanks to all of you who suggested making sure that all my windows updates are current, been there...done that.  Also appreciated those who offered the solution of updating, repairing, removal and reinstall of C++.  None of the above has solved my problem.  I've even had 2 sessions with a Cakewalk Support rep. and they can't solve the problem either.  I've been a Cakewalk user since the original version 1 midi sequencer days, and the is the first time I'm actually considering going to another product.  Frustrated..... 

I may have missed it in earlier posts (apologies if so) - can you tell me which release was the last one that functioned properly for you?
 
And, IF you were using Command Center for your installs, did you try doing a rollback to that last good working release?

Can you please go to Control Panel > Uninstall a Program, and scroll down the list to see what your latest C++ run-time version is - and post that here?
 
Also - there were a couple times where Windows Update said it was up to date, but in fact there were additional updates to install that were not detected because of a MS bug in its maintenance searching process.
 
They provided the following to help address that:

Have you looked into the above?

There was another post where someone was having trouble getting Sonar to install, and they tried something a bit different - and it worked for them.
 
They went to Control Panel > Uninstall a Program, and scrolled down to find the latest C++ runtime version, and then clicked up near the top on the link labelled 'Change' (which is for change/repair).  They then clicked on Repair, and after that finished they had no more trouble with their Sonar install.
 
Might be worth a look.
 
VERY sorry for your frustration - if we keep gnawing on this, hopefully it will get resolved.

I seriously don't think going to another DAW is going to solve your issue.  You have a systemic Windows issue that is preventing the installation of Sonar.  Even if you go to another DAW, those systemic Windows issues are still going to be present. 

Best to persist with resolving your Windows issue.  I still believe the issue is with a faulty Windows update installation.  I think robert_e_bone is on the right track with his suggestions.  The issue, I believe, is with a corrupted MS C++ runtime installation.

jazzy, I can understand it is a pain in the but ho, but seriously, try looking in to the windows update again.
there is a solution.
hope you find it.

Bob, the latest version of C++ is Microsoft Visual C++ 2015 redistributable (X64) -14.0.23918. I have uninstalled and reinstalled it, repaired it.
I have clicked on and followed all of the links for Windows update, used the Windows update fix program. The update program tells me that that I have no more updates.  Also in looking at the update files, there are no failed updates.
 
I have disabled my antivirus program and my windows firewall.  
Also, I bought and ran a registry cleanup program, didn't help.  
 
The last working version of Platinum that I can roll back to is Newburyport.
