[Solved] SONAR Platinum will not start.

Hey guys! I'm excited to get this thing up and running, but there are a few minor issues I need to resolve.
 
Here are the conditions.
 
- Windows 7, fully patched.
- Previous install of X1 Producer, now uninstalled.
 
Here is the problem.
 
1. Installed Platinum.
2. SONARPLT.exe splash screen / loader just hangs and stops responding.
3. Attempted to clear the relevant %appdata% folder, as this site's KB indicated.
4. Reboot and try again. 
5. Back to 2.
6. Tried a "reinstall" from CCC.
7. Back to 2.
 
Has anybody encountered this before, or know how to resolve it?

Yeah, already tried that. This is "first run" too by the way. I've never actually gotten in to the app outright.
 
I'm wondering if there are remnants of past installations, other than the config files, that are messing with it.
 
Does anybody know where the CCC keeps it's downloaded files? I might try uninstalling, cleaning up the file system and registry, then re-installing it fresh.

No. I uninstalled everything, including all my third party things, like Guitar Rig Pro, before I even installed the CCC.
 
All my system drivers are up to date as well. However, I am going through and removing a lot of "little" things I no longer need or use, and cleaning up my file system and registry. In addition, the firewall and virus thing are both off.
 
I am going to try completely fresh, testing each install along the way, to see if I can find where an error might be.

I may have to do that, because I've tried everything. I'm an ex-IT dev, so I know how to cancel processes. That wasn't it. Here's what I've tried...
 
**Making this public just in case somebody has input, but mostly so I have something to review when I call support on Monday.**
 
- Backed up the CCC downloads to another folder.
- Uninstalled everything.
- Cleaned the registry.
- Cleaned file system for everything related to the install, including...
-- %appdata%
-- c:\
-- c:\ProgramData
-- c:\Program Files
-- c:\Program Files\Common Files
-- c:\Program Files (x86)
-- c:\Program Files (x86)\Common Files
- Checked drivers for video card, sound card, audio interface, mouse and keyboard.
- Checked Windows Update, including optional items.
- Rebooted.
- Moved Platinum only files (and sub items) back to CCC download folder.
- Re-installed Platinum, without Melodyne and Addictive Drums for now.
- Updated Platinum.
- Rebooted.
- Attempted to run Platinum to have it hang, and stop responding, at the splash screen.

These have not been suggested:
Disabling the virus scanner during install
Running SONAR as administrator

I figured it out. This information should probably entered into the Knowledge Base, or made into a sticky post at the very least.
 
Problem: Sonar hangs during splash screen initialization.
Cause: Sonar detects ASIO audio card drivers and attempts to connect. If the unit is unplugged, or off, with no phantom power supply, the connection will be left open and unanswered, thus causing the hang.
Solution: Plug the unit in and turn it on!
Recomendations: Update Sonar to utilize a timeout on such connections and automatically re-calibrate to something like WDM or another preferred secondary interface. This is, of course, a development issue.
 
I figured this out by taking the advice above and uninstalling the ASIO drivers. But before I re-installed them, I attempted loading Sonar again. This time it worked. I installed the drivers again and reloaded Sonar, only to have it hang again. It occurred to me that, as I was setting up a new system, and had not moved my interface in to the room yet, I should do that. Once I did, Sonar loaded with no issues.
 
Thanks for all the input and dialog. Hopefully, this will help somebody else in the future.
 
Cheers, Drew

Hmmmm...if an interface isn't connected, for me SONAR has always just loaded Windows audio drivers. Check the taskbar and see if the splash screen is there, but hidden behind SONAR.

I just launched Sonar Platinum using my FastTrack Ultra and it worked ok.

I'm using Windows 8.1.
I always plug in my interfaces so they don't need to get power via USB. If your USB Bus is under-powered, you'd have trouble with your interface.
 
Firewire carries more power, so Firewire interfaces sometimes work well without being plugged in.
 
I can add that back in the day, I used to use a couple of channels on the interface without it being plugged in - when using a laptop to do recording.
 
I use the latest drivers from here for the FastTrack Ultra...

I will say the pre-amps on my FastTrack Ultra went bad. It maybe the case on yours too. Bump the buttons on the front to switch to the rear of the interface. Use external pre-amps and see if that fixes things for you.
 
if you are using it USB Powered, definitely switch to Rear for all channels not in use to bypass the pre-amps.

Found my solution to the exact same (Sonar hanging at splash): Deactivated all audio devices I do not use in the device manager of Windows. I had things like a USB Dock audio device, NVIDIA Audio devices etc there. Deactivated all but the one I need ... and voila, it finally starts up right. 

I am trying to demo the Sonar Platinum and it poofs after splash screen shows for 1 second.
 
Everything else is peachy on my Windows 7 here.
 
So I tried to uninstall but it doesn't show in the Programs and Features.  How do we uninstall?
