It would probably help if you can get a handle on the terminology here and (if necessary) put up a new post.
Huawei is a cellphone network type modem. You need to speak to your cellphone provider if they supplied it. Or the retailer who sold it to you.
Because, according to your text, Huwaei install software is either lacking something or you are trying to install it on a different version of Windows than it's intended for.
If the "internal modem of the Modem" you refer to is an internal wireless adapter in the laptop, that is different technology, designed to connect to a home-type 802.11 wifi system.
