CH341SER USB DRIVER FAIL INSTALL
The driver should now install successfully. After that, the CH340 -based board should appear in the "Ports (COM & LPT)" section of the Windows Device Manager device tree as "USB-SERIAL CH340 (COMn)" and the board should show up under the Arduino IDE's Tools > Port menu. Select the folder of the unzipped CH341SER.ZIP you downloaded from the WCH website.Click "Browse my computer for drivers".

CH341SER USB DRIVER FAIL ZIP FILE
zip file and install the drivers via Windows Device Manager because some driver installers also install additional applications to manage that device and I only need the driver itself in this case. I actually think I have only ever used the driver installer once. I had not, but I just gave it a try and had the same problem as you. Have you tried it on one of the later feature updates on Win10? But, I've searched quite a bit (over the last 2 hours) and I keep winding up on the same threads from 4 years ago, nothing more recent is coming up & those solutions are not working. I apologize if this has been recently covered. I've had other issues with programs being blocked with no option to unblock them in the past few months leading to large amounts of frustration. I suspect Microsoft's recent over-enthusiastic "protect users from themselves" Apple mentality is to blame. I also tried on my main PC (also newer than the last time I tinkered with an Arduino) and it's also failing here with the same nondescript error. I've tried compatibility mode and disabling driver enforcement (as recommended on this forum as far back as 2017), but nothing is working. The installer will launch, but when I click the install button I get "Driver install failure!" I've downloaded several times from multiple sources. I know I need to install the driver for the CH340 controller to work properly, but I can't seem to install it. I've got an old laptop (2nd gen i7) with a fresh install of Windows 10 Pro 21h1 that I'm using in my new workspace to get back into tinkering, which I haven't done in several years.
