Windows 7: ActiveX component can not create object

I found this tutorial about Activex component but I am getting an error under Internet explorer 8 and Windows 7 pro: "An ActiveX component can not create object"

this tutorial is working fine under Windows 2008 Server R2.

Windows 2008 Server R2 is designed for 64 bit. My 1st bet is that you built a 64 bit ActiveX, and you are running IE (32) on Windows 7. Make sure that your project target is set for x86 and not AnyCPU or x64.
