SpeedStick IV LTE (Alcatel W800) missing driver (Windows 7/10)

I own Alcatel W800 (SpeedStick IV LTE) usb stick which I brought in 2017 from T-Mobile.
USB is working just fine as wifi router (it has wifi option and normal usb), however I can't install drivers because installation file got corrupted.
When I connect USB to PC, it is recognized as CDFS drive with 12Mb installation of drivers.
So when drivers are installed (Internet manager by T-Mobile for this Alcatel) I can connect to internet on pc.
However as setup.exe is 340KB corrutped I need to download drivers.
I searched on all internet, contacted T-mobile who said "contact Alcatel" and Alcatel told me to "contact T-Mobile because "Internet manager" is not their product".

So does anyone maybe own this device or can help me find drivers for it on internet?

I also uploaded zip file of drivers which are on my Alcatel W800Z but one file is corrupted

Hey, please check out the device manager. There you will have other or unidentified devices. Open the properties of such devices. Go to the "details" tab (if I remember the Polish name correctly). There, expand matching identifiers and copy them to the thread. I think this will be the fastest way
