Hi Gabrijel
I see the same issue on win7. I solved the issue with below instructions.
- follow http://wiki.seeedstudio.com/Seeed_Arduino_Boards/ to install wio gps tracker into board manager
- then open the arduio ide, click file–>preferences–> click the link as below picture
- you can see the address, such as C:\Users\xyu6\AppData\Local\Arduino15
- from device manager, please select the above address as the location to scan for the driver.
it seems the drivers on wiki does not work any more. the above address also has the driver. we will update the document later on. thanks.
best rgds
Bill
