I just updated to the latest version of Audacity and before the latest one, my Auto-Tune 7 VST plug-in was working just fine. Now, everytime I try to use it, a pop-up appears in the screen saying,

“Effect Failed To Initialize
Attempting to initialize the following effect failed:
Auto-Tune 7 VST
More information may be available in “Help>Diagnostics>Show Log””

I do not understand what’s happening. I have watched every video related to this problem, still nothing. LAME and FFmpeg installed. Everything’s in order like always, nothing was changed. I hope that you can help me. Thank you very much.

The version number can be found in “Audacity menu > About Audacity”
Which version are you using?
Do you have the 32-bit or 64-bit version of Auto-Tune 7 VST?
Do you have a full licensed version of the plug-in (not a cracked version or trial version)?
