I have bought it one hour ago  Try to convert a cr2 from V3 to V4 (bought v4 license)
The conversion seems ok but the progam create lot of folders in 2 runtimes ( in P5 where was my original V3 file and  in P7 where is the v4 folder) in caracters folders and in geometries folders ,two kinds (Eviinnocence folders and !converted folders)
But nothing in each folder just folder
Why not a just save as option ?
Why all these folders?
I am not sure for now  i did a good thing
WW was ok even it is a little bit longer to use
