Can not open file as archive

HI,

Attempting to update the firmware on my UQ2, reading the PDF that comes with the firmware download it mentions to click a link to silabs.com to download the required driver - CP210x_VCP_Windows.

Trying to open the zip file using 7Zip I just keep getting that error - 'Can not open file'. 'C\user\blah blah CP210x_VCP_Windows.zip' as archive.

What's going wrong?  I've updated the firmware before and not had this issue.

Edit - It says when downloading the file will be 3.7Mb but once it's downloaded it's 0Mb.

Edit #2  I went straight to their website - https://www.silabs.com/product...t-bridge-vcp-drivers and downloaded it form there, working now.
