Hi There
Only ActiveX that RS is using is ordinary MS TreeView and that is for RS preview form.
Treeview is contained in MSComCtLib
For 99% percent of machines no separate registration is necessary because
some other application already did that bit (like MS office apps)
If this is clean Vista instalation with very few apps on it then perhaps
you will need to manually register ActiveX
Here are some links I found on this
