Getting error "The driver of the coprocessor is not installed"

Windows update should provide the coprocessor driver

Install a driver for this device cannot find the device driver.

Hi, @PBEKAL :

Go to the device manager and click on the coprocessor device needing the driver.

Then click on the Details tab at the top of the coprocessor window.

Now you should see a Property drop down list and it will be set to Device Description.

Drop down on that list and select the 3rd item (Hardware ID's).

Post the top string of characters that you see in the window, so we can try and figure out what device it is that needs the driver.

Hi:

You need this driver...there are only drivers up to windows 7 for that device.

Manually install it if the auto install method doesn't work.

[PBEKAL]

Manual install did not fix the issue.

[Paul_Tikkanen · Accepted solution]

The hardware ID you posted is present in the driver, so the manual install should have worked (unless the W7 driver is not compatible with W10).

I have pulled the driver from the file, zipped it up and attached it below.

Download and unzip the file to its folder.  Do not do anything with the files in the folder.

Go to the device manager and click on the coprocessor device needing the driver.

Click on the driver tab.  Click on update driver.

Select the Browse my computer for driver software option and browse to the driver folder you unzipped.

Make sure the Include Subfolders box is checked and see if the driver installs that way.

Then reboot the PC.

Which hardware type to select ?  Coprocessor is not an option.

[Paul_Tikkanen]

You click on the device where you got the hardware ID from.

If that device no longer shows up then the driver already installed successfully.
