I just downloaded a reverb convolution plug-in. I put the .dll file into the folder: /sleinberg/cubase essential 5/VstPlugins
But it does not show up as an available insert for an audio track or in the Plugin information window.
What am I doing wrong?
Did you set the path in VST2.x Paths? Is it Blacklisted? Check the Prefs Files link in my sig re: blacklist.
I do not know what you mean by this
But yes I did select the path.
There’s a blacklist.XML file in the Cubase App Data folder. See if it’s listed there. If so, delete the file and re-start Cubase.
System drive \Users< your username>\AppData\Roaming\Steinberg[Application]
I don’t have an AppData folder there.
You should be looking for the blacklist.xml file there. 
I found the file. the AppData Folder was “hidden” I will have to wait till I get home tonight to try it out. I don’t have my USB Key. What is the deal with the blacklist? What is the purpose of its existence?
To let you know if Cubase doesn’t like a plug. Like I said, sometimes it just takes another scan to be ok.
The plugin is still not working. I have deleted the file Vst2xBlacklist.xml 4 times and every time I search for it, it is still there.
It will always be there. The thing is, is the plug listed in the file or not?
Yes it is. Sir2 is the Convolution Reverb that I want to use. Is there anything I can do to not have it blacklisted or am I out of luck with this plugin?
I’m having exactly the same problem but with Waldorf Edition 1.7.3 on my Windows 7 64-bit, Cubase Studio 64-bit 5.5.3. I got the plug-in’s latest installer, a 64-bit version, from Waldorf Support, but no matter what I tried, the plug-ins (3 DLL files Attack, D-Pole, and PPG Wave) always get black listed. The 64-bit installer installs both a 64-bit version and a 32-bit version, but neither seem to register correctly with Cubase Studio 5.5.3. I notified Waldorf’s support and am waiting for a response. My hypothesis is that Waldorf’s new DLLs for this plug-in do not validate against VST standards.
Same here. I have W7 64 bit and Cubase 6 64 bit and can’t get Waldorf Edition to install. I have exchanged a couple of e-mails with their support with no luck so far. I’ve been desperately dragging the Waldorf folder to almost every “plugin” folder I can find. Nothing works. In my case it doesn’t appear in the blaklist file for some reason. Has anybody got the Waldorf Edition to work in 64-bit environment?
I did get this to work. The VST DLL files are fine, so my hypothesis was wrong. For a while, they were showing up in my xmlblacklist file. I wish I remember what actually fixed it. I now have a separate PC only for music where I have the UAC disabled. That seems to help. I would recommend at least testing it without UAC enabled. I can provide some details about my file locations and Cubase configurations if anyone wants.
i finally figured it out - the issue is with “VST3” files NOT 64bit “dll” files. For whatever reason Cubase only recognizes “VST3” files if they are located in the Program Files\Steinberg\Cubase 12\VST3 folder
I simply copied all the “VST3” files from the spot IK Media puts them into and then a restart of Cubase 12 makes everything work. Why Cubase’s VST Manager cant understand a “VST3” file is anyone’s guess
Enjoy!!
I am reopening this topic,
I am in Cubase 11, I just installed the Kontakt 6.7.1 update, however in cubase I only see VST3 and I don’t see VST2 even though I installed both versions.
What could be the cause? VST2 is not black listed and is in the usual path
I just saw your reply, can you be more specific in the steps? thanks!
I cant see kontakt VST 2.4 and VST 3.7.1 at the same time! in order to do so, I have to hide one or the other.
