C # Check whether the driver is installed

# Region: Check whether the CCD driver is successfully installed. String Path = @ "C: \ windows \ system32 \ drivers \ usbcamif. sys "; // The default installation address of the driver if (file. exists (PATH) {} else {MessageBox. show ("the driver is not installed. Update the CCD driver first. "," System prompt ", messageboxbuttons. OK, messageboxicon. Warning);} # endregion

First, paste a code to check whether a specified sys file exists in the drivers folder. If a driver already exists, you can install the driver.

But now I have no hardware device on hand. I cannot insert a USB, and then find the driver in the Device Manager to install the driver. That is, the corresponding driver registration cannot be completed. Naturally, the corresponding file cannot be found in drivers. After packaging C #, click EXE to automatically install the driver .. This eliminates the need for manual installation. What should I do?
