Please see my comment to the question. The thing is: the question, as formulated, simply makes no sense.
I'm not sure you are aware of purpose of regsvr32. It registers or unregisters ActiveX control or other COM components in system registry:
regsvr32[
^],
Regsvr32[
^],
https://support.microsoft.com/en-us/kb/207132[
^].
So, first question would be: do you really want to create a system-wide control or COM component to be registered and why? I, for example, would not do it at all. But if you really have reason to do that, the second question would be: why you don't develop such component and instead try to register… who knows what…
