C4 scans all plugins everytime it starts...takes forever

i just built a new computer (win7 64) with C4 until i get C6 working and everytime i start C4, it scans my waves plugins like it was the first time it has seen them. this didn’t happen on XP. any thoughts on how to remedy this? where C4 usually takes 15 seconds to load, its like a minute and a half.
