Cannot register MSCOMCT2.OCX using regsvr32

Hi there TechNet-ers !

First, here are some specifics,

My PC: Acer desktop model M5810
My OS: Windows 7 Home Premium 64 Bits
My PC account setup: As Administrator
My problem: registering MSCOMCT2.OCX (Microsoft DatePicker) (with the aim of using this control on a UserForm within Excel 2007)
My context: Using VBA to enhance my personal Excel 2007 documents.
My status: I do pretty well in VBA but am no professional programmer

Here is what I did:

1) I copied MSCOMCT2.OCX to the C:\windows\SysWOW64 directory

2) I clicked the Start Button and used the Run application to run this command:
    regsvr32  c:\windows\sysWOW64\mscomct2.ocx

3) I got this reply: "The c:\windows\sysWOW64\mscomct2.ocx    module has been loaded, but the call
    to DllRegisterServer has failed, with the error code 0x8002801c"

4) After having googled "DllRegisterServer" somewhat, I'm left with the impression that what I must do is to find a way of telling Windows that I want to run that command in Administrative Mode. I know my PC account is already set to Administrator, but it seems this is not enough and that Windows must still be told to run the command in Administrative Mode. But I don't know how to do that. Or is it really a matter of Administrative mode ?

5) I've repeated the same steps, this time with mscomct2.ocx copied to the c:\window\system32 directory but I get the same error message as before. Can somebody provide some help ?


Thanks for listening
