I am getting frustrated! I am having a huge difficulty with Sonar recognizing Waves plugins. It started right after the previous update to Platinum. Upon startup there was a popup that stated that several plugins that I used in the project I was loading into Sonar were not available and may not have been installed properly. These were plugins I have used successfully for some time without a problem and all were from Waves. On the phone to Waves support and we eventually got them back, but only after reinstalling Sonar. The issue recurred several days later. I tried all the probable fixes attempted during the session with Waves to no avail. In the meantime I attempted to contact Cakewalk support. It took 9 days for Daniel A. to respond for which he did apologize, but only offered the usual fixes which I thought I made clear had been tried. Back on the phone to Waves and after some remote poking around he said I guess I would have to try and reinstall Sonar again, which I did. Twice. I have the latest updates for all products concerned. I had already replied to Cakewalk twice and it has now been five days. I have been a happy Cakewalk customer since Pro Audio 6 in 1998, but now not so happy. Any help would be appreciated.

Could the update to Sonar have removed the directories that your Plug-In Manager searches for the Waves plugins?

Sounds like the automatic scanning might be problematic for some reason in your case. Do you keep your Waves license on an iLok or is the machine authorized?
 
You should be able to switch the scanning mode to manual, do a full reset, and then a full scan and be able to use them again.

1. Go to Preferences | VST Settings and set the scan to Manual Scan
2. Turn ON Rescan Failed Plug-ins
3. Turn ON Rescan Existing Plug-in
4. Click Reset
5. Click Scan
6. Wait for the scan to complete
7. Check for Waves plug-ins

If all is good you'll want to turn OFF Rescan Failed Plug-ins and Rescan Existing Plug-in. That way your scan time isn't longer than it has to be the next time you add a new plug-in.
 
Hope that helps,

I had the same problem, twice now, over the last month or so-but never before that. Of course what Lance said is correct and that's the same thing that I had to do also, and it did work. I somehow suspect something happening at Waves that they are possibly working on. Sorry, other than what was said already, I don't have anything other than sympathy for you-hang in there!

I had the same issue... Waves Central was the problem in my case, coupled with what I think was a Windows Security update. Update Waves Central and reactivate the licenses. I THINK that's how I fixed it - there was a lot of clicking, downloading and cussing.

Well, I tried all known and relayed possible fixes and the Waves FX are still no longer recognized in Sonar. They work fine in Sound Forge and all installed Waves plugins appear there. I redownloaded Waves Central after removed all traces of Waves products from my computer. Reinstalled Sonar from online products page. Scanned and rescanned after reset in Sonar, started with a new project after reopening Sonar, all to no avail. This is a really wacky problem. As I said they work fine in SF. I have too much time invested in Cakewalk to switch to Abelton now - just kidding sorta, but something weird is happening here. Thanks to those who gave it a shot so far and please continue to try to help me. Any other ideas, folks?

Could be that sonar is excluding them. Try rescanning failed plug-ins. I gather you went to the %appdata% and wiped the cache and also the waves central directories.

One other thing check your license cloud and where the licenses are being stored.

Contact Waves support. I've had some issues over the years, and they've always been prompt and helpful.

Not sure if it is related to your problem, but here's what I ran into with my Waves plugins. On my laptop, I have to disable my Ethernet network connection in order to make LatencyMon happy. The Ethernet port has to be enabled in order to install Waves plugins properly with Waves Central, so after installing Waves, then disabling the Ethernet port and going back to just my WiFi connection, Sonar would not recognize my Waves licences. I had to re-enable the Ethernet, transfer the Waves licences back to their cloud, disable my Ethernet, go back to Waves Central while on WiFi and transfer the licences back to my computer, then rescan plugins in Sonar... now every Waves plugin runs nicely in Sonar. I have to do this process every time I buy a new Waves plugin. I use Sound Forge as well, but I've never tested the situation with it. -Mark.

Thanks again to all those who are offering help.
 
interpolated: Yep, done all those things. Started fresh. Same issue.
 
Anderton: Been on the phone with them twice. The first time we got it to work, but the problem recurred. Reinstalled Sonar again (which seemed to work the first time) but now the Waves plugins work with anything but Sonar.
 
ryecatchermark: Computer with Sonar is on ethernet, but no wifi (desktop).
 
Could it be some sort of scanning conflict? Below are my scan paths exactly as they appear in Sonar Preference:

C:\Program Files (x86)\Cakewalk\vstplugins\cakewalk sound center
C:\Program Files (x86)\Common Files\VST3
