Can't re-open Audacity

I’ve installed reaper ReaPlugs VST v2.36 64-bit but after set in Audacity ->Preferences → effects → Grouped by Type then click to ok starts a loop that open a window with write this message “Impossibile inizializzare l’effetto” and to every click on the “ok” button of that window, start a new window with the same message but a different effect name for example “mda MultiBand”, “mda Loudness”, “mda Dither” in a never ending loop.
I’ve try to uninstall audacity then re-install it but the problem still remain.

How can I fix this problem? Someone has the same situation?

Sorry for my english, thanks to anyone will try to help me!

Audacity for Windows is a 32-bit application so 64-bit plug-ins won’t work. Some 32-bit VST plug-ins work but I don’t know about ReaPlugs. I’m sure they don’t officially support anything other than REAPER, but they still might work in Audacity or other hosts.
