Today I updated the control center then
- DL & installed all updates then
- lost my desktop shortcut Sonar Prof Icon
- tried to launch from the control center & got the following error message
 
can't start SONARPRO.exe system error
api-ms-win-crt-runtime-I1-1-0.dll                    is missing
 
Then reinstalled all of the Sonar Pro components parts again from command center.
Still no desk top icon & same error message
So re-booted computer - no change.
 
what is that dll   ??
anyone got a fix ?????
 

I'm having similar problems to the above so tried installing the c++ libraries separately. However, this wouldn't work and failed with an 'unspecified error.' So what to do next?

Did you try the automated trouble-shooter that I posted above?

Had the same problem. Solved with installation of the two C++ 2015 redist (downloaded from Microsoft).
Thanks...

PS: Solving this issue, I found and cleaned my PC from rootkits :-)

I can't install the C++ Redistributable 14.0.23026, it hangs on "Windows7_MSU_x64". So I can't continue with Sonar until I upgrade to Windows 10? Good job!

Win10 is not a requirement. I do not believe other users in this thread had to do anything other than run the appropriate updates for their OS.

The problem is, I can't do any updates on Windows7 anymore. They changed something at microsoft so the Windows Update is broken. At least for me and a whole bunch of other people.

Did you try the utility linked in msg #8 above?

Having the same problem as other posters here.  I didn't update Windows 7 for the past couple of years, so that's probably the problem--but who knew that Sonar updates would depend on that--or else they'd blow up completely?  Things were working very well on my computer until the recent Platinum updates.
 
This is how it went down:  First, I tried to update Platinum from Command Center, and the installation failed. Reason given:
"api-ms-win-crt-runtime-l1l-0.dll is missing from your computer.  Try reinstalling the program."
 
Platinum was also automatically removed from my start menu.  I still had a desktop icon, and tried to launch it and got this messge: 
"Unable to register the DLL/OCX:  RegSvr32 failed with exit code ox3.  Sonar has a support page for that error.
 
Ok--then tried to update Win7 with updater--some updates failed, and I didn't get the one I needed.
Then--Windows Updater got locked up.  Didn't work for over a day.
 
Tried the Microsoft automated troubleshooter.  It said it fixed my updater problems.
 
I'm taking the last step on the Sonar Support page and reinstalling Microsoft Visual C++ 2015.  Support gives the link to Microsoft.  First attempt--the message told me it's already on the computer and to uninstall and reinstall Microsoft Visual. 
 
That's where I am right now.  I've been waiting 5 hours now while the installation says it's "Processing."  How long does it take?  Is it hung up?
 
Did you other guys solve this, or did you give up on Sonar?
