Hi Keni,
I just installed my free one knob louder,and all 4 versions turned up-32 bit mono/stereo,64 bit same.
I had the "only the 32 bit would show" when I first tried Waves,and it was the Kramer tape that would only show in 32 bit.
I got in touch with support,and they told me to delete anything in the VST part of the regisrty that refferred to wavesHKEY_CURRENT_USER \ Software\ Cakewalk VSTx64 \ Inventory,and thats what I did but I ended up finding another reason for why,the 64 version wouldn't show,and for the life of me "I can't remember",but it was something to do with reinstalling all the Waves plugs again.
I'm sorry I don't remember,but the answer occurred when I was in the regisrtry,I just wish I could remember exactly,also don't forget to make a backup of the regisrty first,and the section I wrote just now,is pasted from the support email. Good Luck! Bob [font="'arial','sans-serif'; font-size: 10pt; mso-ascii-theme-font: minor-bidi; mso-hansi-theme-font: minor-bidi; mso-bidi-theme-font: minor-bidi"]
