One or more components required to run this plug-in may be missing.
All of my audio plugins say this and I haven't been able to fix this in months, can you help me fix the problem and to find the folder of the Audio FX?
"One or more components required to run this plug-in may be missing" - As I recall this is usually a preset plug-in error after one or more of the plugins has been deleted or moved.
Most of the VST FX <.dll> files are typically the 'Program Files' and 'Program Files (x86)', By default, some VST installers create a 'Steinberg' folder or put them there if it already exists. Others, like Waves and Plugin Alliance create their own folder' in one of the Program Files folders. Most <.dll> plug-in file(s) can be moved to another folder if desired. The DX plug-ins cannot.
In any case, go to "Options> Preferences> VST Effects" and select the default and alternate folders.
In that case, I would do a complete uninstall/reinstall, using a third-party uninstaller app (like Revo's Uninstall), That will remove the registry entries that the Windows uninstaller leaves behind. NOTE: This will remove your user FX presets as well. It's a pain, but I can't think of anything else off-hand, except tech support, and they may recommend the same.
