"Sonarplt.exe has stopped working"?

The experts will show up here eventually, but I suspect it's related to that ASIO4All driver.  What audio interface are you using?

I'm using Sonar Platinum version: 22.7.0.41. At the time this happened I was trying out a new ART TConnect USB guitar 1/4inch-USB cord. I had set the audio input to the asio4all driver but got not sound from my speakers.
 

I kept getting this error with Windows 10. I tried 7 times, but I'm back to Win 7 again.
This is a real issue.

Do you have an audio interface, or are you using the built in sound card on a laptop or desktop?

Sorry for the confusion. I'm using a Dell XPS desktop computer running W10. with the built-in Sound Blaster X-Fi Xtreme Audio sound card. Does that help?

I'm spit-balling, but I wonder if you can disable the Recording and Playback devices in Win and then open SPlat.  I think you'll get a warning message about there being no audio device, don't know if it will crash or not.
 
The pros here will give you some better suggestions I'm sure:)

Hi Scott and other contributors to this post:
Thanks for your help. I tried disabling the recording and playback devices, but that made no difference. I'm aware that SoundBlaster is no one's choice for a professional soundcard, but that's not the issue here, as far as I can tell. I'm still waiting to be contacted by Tech Service. Hope I don't have to wait forever!!!

Hi Stevec,
 
Thanks for the advice. I don't know were to find the aud.ini file; it's not coming up in my SonarPlatinum program file.
 
I tried opening Sonar with Ctrl+Shift held down, but got the same "Stopped working" message as before. Still no word from Tech Support.

Hi Chuck,
Thanks for the help. I tried a rename of the AUD.Ini file and deleting it, but I'm still getting the same result.

your running low on options so this is what I would do.
 
Hold down the CTRL key and start sonar (use the icon on the desktop) Not shift + Control.
just simply Control.
hold it down while double clicking the sonar icon on your desktop.
to be honest ive never heard of holding down CTRL+SHIFT at the same time, maybe steve knows something I don't but I don't think so.
so hold down control and try to strat sonar.
if this doesn't work, move to plan B:
 
If your program will no longer launch, you may be able to resolve the problem by forcing it to re-write some settings behind the scenes. To do so, follow these steps:
1.               
Hold down the Windows key on your computer keyboard, then press the R key to open the Run prompt.

2.               
Type in the following: %appdata%\cakewalk

3.               
Click OK. This opens the Cakewalk content folder in Windows Explorer.

4.               
Right-click the SONAR folder and select Rename on the pop-up menu.

5.               
Change the folder's name by adding the word “backup” to the end of it. For example: “SONAR Platinum backup”.

6.               
Close Windows Explorer and restart SONAR.

7.               
When prompted with the message “SONAR will now personalize your user settings”, click OK.

Chuck,
I've tried both those suggestions: the control start tried to initiate but I got this message: "Your personalization process didn't complete. You may have canceled the copy...Please redo the personalization if necessary." I don't know what that last live means.
 
I tried your plan B with the same results as before, only now I have a Sonar Plat and a Sonar Plat Backup folder on my computer.
 
To promidi: I wish MS had told me that I needed to turn on SystemRestore when I upgraded from WIN7 in June, but they didn't, so I'm not able to restore to a time before this event happened; but thanks for the advice anyway.
 
What does anyone think of the idea of uninstalling Sonar Plat altogether and once and for all, and then reinstalling again? I reinstalled after it stopped working, but I can't remember now if I uninstalled the "broken" version. What's the worse that can happen?

Hi Chuck,
 
Thank you for the continual attempts to help me fix my SonarPlt problems. So far nothing seems to be working. By the way, my Win10 system is up to date, as are the drivers for my various sound and video cards. I tried the Ctrl-Shift tip and got the same result. I've turned off my anti-virus software and tried to launch Sonar with the same result. I haven't uninstalled-installed yet.
 
I'm disheartened by the lack of any response by Cakewalk Technical Support. This problem is now 10 days old. I've spent lots of hard-earned cash on Sonar like you and probably many other Sonar users on this Forum, so I expect more than an email promising to get back to me within 3-4 days. Have you or anyone else on the Forum had any dealings with the Technical Support department? Are they really THAT busy? Are there too few of them? Doesn't Cakewalk care about its user base?

Since Platinum worked after you upgraded from Windows 7 to Windows 10 in June, until recently when it suddenly stopped working, you need to ask yourself what changed around that Saturday or since the last time you launched Sonar without issue?
 
It looks like the smart guys here have covered the Sonar bases thoroughly, so I'm going to go out on a limb here and ask about Dell drivers and Windows updates.
 
I did notice on the Dell support website for the XPS 8300 the disclaimer "Product not tested for Windows 10 upgrade".  http://www.dell.com/support/home/us/en/04/product-support/product/xps-8300/drivers
 
Perhaps it is possible that a recent Windows update slipped in some drivers that it thought were better than what you had that were working?
 
I had an experience like this with the August update to Version 1511(OS Build 10586.545).  My Windows sleep mode went completely FUBAR after the update. After investigating, it turns out that there was a hidden update to my Asus chipset drivers for Intel IMEI.  I re-downloaded the driver set that I had installed from the Asus site when I originally installed Win 10.  When I tried to re-install the Asus version, Windows complained that there were already newer files onboard!  I bypassed the warning and re-installed anyway. Problem solved!
 
I'm not suggesting that this is your problem, just that Windows 10 updates can do some crazy s***!!!
 
Take a look back at your Windows update history and see if any updates were installed around the time your problem started.  Possibly you could try rolling back an update, or uninstalling drivers and replacing them with original Dell drivers.

user32.dll is part of Windows not SONAR. I found it in C:Windows\System32

There is also a check you can run for missing or corrupted Windows system files ...
 
System File Checker is a utility in Windows that allows users to scan for corruptions in Windows system files and restore corrupted files. This article describes how to run the System File Checker tool to scan your system files and to repair missing or corrupted system files. If a Windows Resource Protection (WRP) file is missing or is corrupted, Windows may not behave as expected. For example, some Windows functions may not work, or Windows may crash.
