Ok, revisiting this issue. Is there updated instructions or any tips for getting this driver to work on Win 8.1?

My GMC-320 displays as this and there is no driver rollback option. I tried updating it with the update driver option which didn't work either.

Hi Gewehr, maybe you can uninstall the driver first then install an old version driver?

What do you mean? There is only one driver posted on the downloads page and it is good for XP to Win 8.1.

Try to uninstall the driver and try maybe your version of windows has build-in ch34x driver.

If not, can you try to uninstall the driver and try the drivers from these links?

https://www.arduined.eu/ch340-windows-8-driver-download/

Have not tested the second one.

Neither of those work for me either, they seem like they are identical versions anyways. Uninstalling it doesn't make it work either since it seems like it never really installs it in the first place even though it says so.

did you try to install it on another pc?

sometimes with the old version of windows it is necessary that the peripheral was disconnected to install the driver.

you can also find the latest official version of the driver suporting windows 8.1 on the website of the chip manufacturer used by GQ:
h**p://www.wch-ic.com/downloads/CH341SER_ZIP.html
but keep your GMC-320 disconeted from your PC to do driver installation

Mastery is acquired by studying, with it everything becomes simple

I have it installed on an old Windows Vista laptop just fine. I extracted the ZIP you linked, and when I run the exe it gives me this.

Check that there is not too much USB device connected to your PC, some PCs do not support more than 6 or 7 devices.
Try to change USB port, to test, connect your GMC device directly on your PC, and not after a Hub.
After if it doesn't work, may be that the windows registry of your windows 98 must be corrupted, it happened easily with this version of windows.
forget the driver that I indicated to you, it apparently has specificities. and prefer that of EmfDev.

you can try to do the following operations in the following order:
- uninstall the driver
- disconnect the GMC device
- reboot windows
- install the driver again
- reconnect the GMC device

There is only 1 other USB device connected (my wifi dongle). I have been connecting the GMC-320 directly,
and I tried using the older legacy USB 2.0 instead of the blue 3.0, but it still didn't work.
I even tried using the old USB driver (#19 on the download page). I'm using Windows 8.1, I don't know why you think I'm using Windows 98.
