I am running Sonar X3 on a Dell All in One and Windows 10.
Recently, whenever I have done an update as per the computer request, Sonar X3 is no longer functional and I have to re-install
from scratch.
Besides not updating the computer, is there an other way to solve the issue.
Today I will have to reinstall  for the third time.
 
Thank you for any help.

Run X3 as admin.
 

Thank you Gustabo.
I tried it and got the following message: " the code execution cannot proceed because mfc110u.dll was not found. Reinstalling the program may fix the problem."
 
Help.

Never mind

Yes this must be the 12th thread with the missing dll. message issue and now it's hitting x3 which more or less proves this must be W10 and not CCC or Sonar. 
The fix is to make a back up of your Cakewalk folder to another location or drive. 
You'll find the dll in question will show as a 0 bytes when checked with properties. 
All you need to do is copy from the backup and overwrite the corrupted dll. 
 
 

Cactus Music, the only drive I have on the computer is drive C. However I have a couple of external drives where I can copy the Cakewalk folder. Would that work?
Also when I copy from the backup, do I copy back to drive C?
 
Thank you

Yes this must be the 12th thread with the missing dll. message issue and now it's hitting x3 which more or less proves this must be W10 and not CCC or Sonar. 

Those were (CjLibrary.dll and TTSlibsndfile.dll)
 
 
done a search on that DLL (mfc110u.dll) yet ?
This is a windows DLL, Not a Sonar one. not really something you want to be copy/pasting in your windows syswow64 folder.
 

It seems that the solution is to reinstall Sonar X3 for the 3rd or 4th time.
Correct.

Well every thread had a different dll that was showing as 0 bytes. Mine was Overloud.dll.  So its not just one dll it almost seems random. 
If what Chuck is saying is true then re installing Sonar would not fix the issue. 
 
People were re installing Sonar to fix the other dll problems but all that is needed is to replace the contaminated dll with a healthy one from a back up file. 
You can make the back up file anywhere you choose. Just don't put it in the root of C drive as that will confuse windows. This might not be your issue but I'm putting this information here as others will google this issue and it might help them. 
 
When you get the message make a screenshot. Then you can follow the pathway shown to find the corrupted dll. 
 
Then you'll have to see what can be done, If this is not a Sonar related dll you better follow through possibly logging on to the Microsoft help forum https://answers.microsoft.com/en-us/
I've had mixed results but often a person will answer with the best solution to MS issues. Or you find others had the same problem. 

Thank you. Will try anything. It is not the first time this has happened to me.
