VSTs don't show up

[mowgli]

I have a bunch of vst's in a folder which I've added to the preferences, they worked fine with res5, I'm on 6.1.4 and they just don't show up, I've even tried copying them to plugins/afx but no luck either. Any ideas?

Perhaps a 32 bits res5 / 64 bits res6 incompatibility
