Active X control installation issue

Hi,

i  just downloaded the software from the webpage and installed the Active  X control as I did many times with previous versions. However, under the developer tool in powerpoint 2010 the Accelrys  DSVisualizer Control is missing. I am working on a 64-bit Windows 7  enterprise system with an Office 2010 professional installed. Did  anybody else experience similar issues?

Best,

Christian
