Cann't register an ocx in WIN7

I have an ocx,and it can be registered successfully in WIN XP,but failed in WIN7.
I use regsvr32 to do so,but also falied.It said,can't find module.
Is there anybody who has encountered questions like this?

So it fails with RegDLL and regsvr32? Have you tried InstallLib? If it says module not found, then are you sure the module is there? Also does the module have any dependencies?

Yes,both RegDll and regsvr32 failed.I don't know InstallLib,is it very different from the other two method?

Thank you,the problem was solved,it was because some mfc dlls don't exsit in WIN7.
