The software does not show up as a plug-in in my DAW (PC)
We're using Addictive Drums 2 in this example, but the same principle applies to all our products.
The most common issue when Addictive Drums doesn't show up in the DAW is that the DAW hasn't found the plug-in file "Addictive Drums 2.dll". You may need to change the settings in your DAW so that it is scanning the correct path for the plug-in file.
First of all, run the Online Installer and hit the [Advanced] button. That page will tell you where the 32-bit and 64-bit Addictive Drums plug-in DLLs are installed. If you're running your host in 32-bit mode, then you want to use the 32-bit plug-in file and vice versa.
The next step is to check the preferences in your DAW. The option is usually named "Paths", "VST paths" or "Plug-in paths". In those preferences, add the path to the correct plug-in and then hit the Rescan button. After that, you should be able to load Addictive Drums like any other virtual instrument.
