The computer does not see the Megafon 4g modem. How to solve the problem?

Question

Computer networks

Actually, the subject is as follows.
I recently purchased a Megafon 4g modem. Model Huawei m100-3 black. I stick it into the computer, it is detected and the software installation begins. Everything goes without problems. But after that, the computer simply stops seeing the device. And I rebooted the computer, and stuck a modem into other sockets, and downloaded software from the site - nothing helps. If you remove the installed program and insert the modem, then everything is displayed normally again. I checked it on a laptop - everything is ok there, and it works without problems.

it is written that the fact is that the drivers are not installed on the computer, but from the proposed 3 options the first 2 solutions do not help at all, and I can’t test the 3rd one, because I don’t have the described Drivers folder in the Megafon folder.
