Hi,
Sorry, I misunderstood your first question, I thought it was a bout 3.5 not showing the components, I didn't realized it was about v5 components.
I think what happens here is simple, v5 doesn't install any components, it uses classes instead.
Look at "Structural Changes" in http://tmssoftware.com/site/blog.asp?post=228 for more information.
By the way, we released 3.6 yesterday, which includes TXlsxAdapter, which uses v5 to feed the v3 components, and allows you to use a v3 FlexCelGrid or FlexCelReports with recalculation and xlsx support (as v5 doesn't have those components yet).
but all in all, v5 won't have any non visual components, just simpler classes instead.
