It looks like TH2 doesn't install anymore with the boutique fx bundle. For me it installs the VST3 version of TH3 in the expected VST3 folder path Common Files/VST3/Overloud.
That, in theory, should work anyway based on Craig's earlier post (the Chains will load the TH3 models automagically or sumthin' instead of TH2).
Check it out and see if it works.
The TH3 installing from a the Boutique Suite (instead of TH2) is a whole 'nother ball of wax so I'll not pontifimicate on that just now.
Cheers.
