After reinstalling another version for win7 i had the plugin working no problems at loading, the first problem was about the "system.speech" cause i had a version of win7 lighted with speech recognition removed, then the next error was "Cannot find the requested data item, such as a data key or value" and i don't know why this error was caused with previous version of win7. I got some problems with the sound card on my carpc so i can't fully test it out at the moment but for now maybe the most stable version was the 1.1.0 (? don't remember) the one with single number no speech never gave me errors, but i have to fully test this one when i fix my carpc. Anyway still big thanks for the support and time for this important plugin, is really a good piece for RR comunity
**about net. framework 3.5 watch out because it's part of win7 and is not possible to install apart, so i suggest to install a win7 original / fully and not lighted
update: ok after some restart i got again the error "Cannot find the requested data item, such as a data key or value"..
