Sylenth VST causes fatal error in Sonar 7 Producer, yet it runs fine on a stand-alone-VST player like SAVIHost, any ideas?

Oh I'm using Windows 7

Sylenth1 is a virtual analog VSTi synthesizer


Sylenth1 version 2.2 is ready! Included in this version is an AudioUnit for Mac OS X and a native 64 bit version for 64 bit VST hosts 


So are you running 64 bit?  Sonar 7 was never fully tested on W7. 

They don't say anything about a 64-bit O/S being a requirement. I'd be surprised if they did, given the age of that synth.

Are you perhaps running the demo version? Their site says when you buy the full version you get "all available formats", suggesting that maybe the demo has some restrictions.

Or a crack, Funny how when I Google it the Torrent on Pirate Bay was the top of the list. If I owned that company I think I'd do something about that. Hmm, Might be Pirate Bay pays Google for top listing and the Dude with the VST ain't. 

Its a demo version.. thanks guys
