64 bit version of mscomctl.ocx.
I support an application with over 90K registered users for a international logistics company (the guys with the brown trucks). We can not support the 64 bit version of Office Access because there is no 64 bit version of this library. Converting the Tree Views to use .Net would be cost prohibitive.

a german company (picoware) sells VBA sourceCode - Free of any OCX and API (so also 64 bit with no problem) - a pure continuous subform which acts as a pure treeview. For the moment the docu is german only, but the head behind that idea is translating for the moment and an MVP-collegue showing it on the MVP summit ... www.picoware.de
I've bought it and use it and i'm overwhelmed and absolute happy.

Have you seen this:
The JKP treeview is good for 32 and 64 bit.
