How can Winforms WebBrowser use a plugin which works in IE

Question

I have a Forms.WebBrowser which I use to navigate to a bank's login page. The users enter their credentials and log in. The problematic case concerns logging in with a third party Minikey which is a plug-in (shows in Manage add-ons in internet explorer). It doesn't work with the Winforms WebBrowser (instead, there is an error message from the web page, same as when the plug in isn't installed). On IE this login works fine.
I already tried the following:

I set some registry values: FEATURE_LOCALMACHINE_LOCKDOWN and FEATURE_SECURITYBAND, etc. -
with the latter the webbrowser should have shown the security band where the user could choose to run the plugin, but it did not work on every computer.
I reset the IE options
I Set Zone mapping by using the IInternetZoneManager interface.
Any solution enabling the login would help.
I would add that the problem appeared on Windows 7.1 and 8.1 64 bit machines.
I haven't found any topics relevant to my problem.
Thank you for your help!

I'm afraid it's impossible on 64bit machines ;(

Thank you @Maciej Los!
Why is it impossible on 64bit?
Maybe knowing some more details would lead me to a workaround of some sort.

I made some researches and everything what i know at this moment is that, that WebBrowser component is pre-compilated for 32 bit Windows system.

My job is related about your question. We use web browser control. And some times we need to change proxy for this. But I am beginner programmer. So I can't help you

Thank you @Member 11375116!
Maybe you could provide some information about what proxy is concerned or on which conditions do you need to change it - anything that may lead me on.
Thank you all in advance!

Actually.We login insurance agents's accounts. And companies allow only static ip. So we need to change it. We use registry command for that
