hello,
If you have the command center installed right click on the command center icon select Run Admin...
 
Also if this is not really the problem please provide more info about your system, windows version...

If you click on the gear icon in command center, you'll see what folder the install files are saved in and you can run the install file as admin from there.

thanks for that, found it.

1.  SONAR_Platinum_Setup_21.0.1.254.exe
   
2. Run as admin, with same no install result.

comp stats: Win7 x64, i7, 16gb ram, 7200 rpm HDD
 
 
 
 
 
 

Thanks Dave000, did exactly that.
As soon as the install has completed extracting> Registering files: Stretch.ax, that is when the error occurs.
I have also disabled most boot programs (adobe cloud, etc.)
Unable to register the DLL /OCX:RegSvr32 failed with exit code 0x3

You may need to download and update the Microsoft Visual C++ 2010 Redistributable

Thanks Stevec, I'll look into it. support ticket is also in the works.
I'm the Admin, so if it's a permission thing I'm not sure what changed. (what should I look for?)
 
 

Assuming that you have your antivirus off?

I have encountered the exact problem. Cakewalk techs are very helpful but have so far not been able to come up with a fix. Tried the uninstall, re-install, disable anti-virus, run as administrator, re-download installers route without success. I have submitted a .dmp file that was created when attempting to run Sonar after the installation. I am now waiting on a response and, hopefully, solution. I will update this thread when I have an answer from the techs.

Hi Mike. Thanks for the advice. Yes, I have done that already but, unfortunately, the problem persists.

Old thread alert.
The thread is about ..

Install error - Unable to register the DLL /OCX:RegSvr failed with exit code 0x3

 
Unless you are getting that it would be a lot more productive to start a new thread. Your issue is likely to be different than the OP's anyway so I suggest a new thread nevertheless.

Make SURE Windows maintenance is completely up to date, as there are now Sonar dependencies on Windows pieces that only exist through the installation of Windows maintenance.
 
When applying Windows maintenance, you will need to run Windows Update multiple times, because there are frequently updates to the updates, so you get a 'layer' of maintenance, then you have to check to see if there are updates to that layer - and that will apply another layer, and so on - until it finally checks for updates and comes up with no more to apply.
 
This may well take several passes through running Windows Update.
 
Also, after it applies maintenance, and you restart Windows, it may tell you there aren't any more updates, but it may not have checked after the restart, so run it one more time and see if it really is the end of needing to apply updates.

In case it's of use to anyone else, I gave in and did a complete reinstall (initiated thru HP's Recovery utility, but basically a complete Windows reinstall) and all is well now. Clearly corrupted files that Refresh didn't help. Nothing else did either.

Lots o' time lost on that one.

Oh well.

Cheers.

 
This thread helped me complete first time installation of SONAR Platinum Jamaica Plain Version under Windows 10 on Surface Pro 3. I am new to Windows 10 and had just upgraded the Surface from Windows 7 to Windows 10. I received the "Unable to register the DLL/OCK: RegSvr failed with exit code 0X3" dialog for Classic FX, Artist Instruments, and Platinum Instruments SONAR modules.
 
After reading this thread I checked for and installed Windows 10 updates. Then tried again to install the three SONAR modules that had failed to install running Command Center as Administrator and with the Windows Firewall and AVAST Free AV active. It worked! My SONAR installation is complete.
 
I'm not sure that running Command Center as Administrator was necessary as I didn't try to install the three failed modules as non-Administrator after completing the Windows 10 updates.
 
Though the three failed modules installed fine with Windows Firewall and AV active, I'm not sure the rest of the install would have completed with them active. I had turned the Windows Firewall off for most of the installation and had turned the AV off when I started dealing with the three failed modules.
 
This old thread continues to be helpful!!

Jereb, I'm not aware of a step-by-step process link. This thread is the only thing I'd found. As for me, I used my normal Command Center install process of individually installing each module in the command center expanded list. It's more tedious, but it allows me to better track progress and deal with issues when there are any. To my knowledge, all I did to install failed modules was turn off antivirus and firewalls and then run Command Center as administrator to install failed modules.
