I've been with this program since it was Twelve Tone Music. Now I'm considering dumping the thing and all the time is has taken to learn it. Suddenly, and trust me, nothing else happened, now, every time I try to open Sonar, it stops after about 20 seconds, and then I get this message.
 
"SonarPDR.exe - System Error
The program can't start because mfc110u.dll is missing from your computer. Try reinstalling the program to fix this problem."
 
What gives and why is this so hard? I need some help! Please.....

Oh, and also, for two reasons, I don't want to have to sign into Sonar as an administrator just to be able to use it. First, it's a ridiculous hassle and second, I already tried that and it didn't work.

I am not understanding your second post, anyway please install this:

If this does not work,  please remove and reinstall Sonar (or dump it ;) ).
 
BTW did you run AVG at any stage?

Did you launch the installer with 'Run As Administrator'?  That's important for proper installation, and also for the completion of the registration process.
 
Many folks also have the Sonar icon set to also always Run As Administrator, as it gives you elevated permissions, even if your user account is an administrator.
 
Also, is antivirus software running, and was it running during the installation process?  It can interfere with both installation and execution.
 
I believe this is likely an installation mishap, and you may want to consider removing Sonar and installing it again.
 
Please post back if you need complete instructions for removal (including the registry keys and hidden sub-folders and such).

Bob I did further research recently and it that there have been scenarios whereby this file has been removed by AVG when AVG is being uninstalled or updated. Anyway I'm sure there's loads of other scenarios.

Mfc may stand for Microsoft foundation class. This may be related to the required runtime.

Reinstalling sonar should cause the reinstall of the runtime. Alternatively, you could download and install the runtime yourself.

Quite possible - I do not know if you can recover it from somewhere on the web and have that magically fix the issues, or if you have to or should remove/install Sonar again.

It is a MS routine - looking things up on the web shows it coming up missing for other applications as well.
 
I would recommend having Windows up to date on maintenance, in any case.
 
If it were me, I would remove and install Sonar again, after first running Windows Update until it got all needed maintenance applied.

Oh almost forgot, run windows update first!
 
Update - Just noticed beaten to it again by Bob :) :) :)
