A driver cannot load on this device. Driver:IVrs64.sys

Hi there,

I've recently purchased a new pc and now I'm installing the driver I need to work with my wacom cintiq. It was not working so I contacted Wacom support and they asked if there were any updates to be done. These are the ones I installed:

- Logitech - Media 10/22/2012 12:00:00 am - 13.80.835.0

- Intel Corporation - Display - 31.0.101.5187

Unfortunatelly, now I'm getting this image as I restarted my pc:

"Driver: IVrs64.sys

IVrs64.sys

A security is preventing this driver from loading. You'll need to adjust your settings to laod this driver"

I tried these to make it work:

1. Run as Administrator: Try running the program or installer that is attempting to load the driver as an administrator. Right-click on the program and select "Run as administrator" to see if this allows the driver to load.
   
2. Disable Driver Signature Enforcement: Sometimes, Windows blocks the installation of unsigned drivers by default. You can temporarily disable driver signature enforcement to allow the installation of the driver. Here's how to do it:
   
   • Restart your computer and enter Advanced Startup Options. You can do this by holding down the Shift key while selecting Restart from the Start menu.
     
   • In the Advanced Startup Options menu, choose Troubleshoot > Advanced Options > Startup Settings > Restart.
     
   • After your computer restarts, you will see a list of startup settings. Press the F7 key to select "Disable driver signature enforcement." This will temporarily disable the enforcement of driver signatures.
     
   • Once Windows restarts, try to load the driver again.
     
3. Check Group Policy Settings: Group Policy settings can sometimes prevent the loading of certain drivers. You can check the Group Policy Editor to see if any settings are blocking the driver. Here's how:
   
   • Press Win + R to open the Run dialog, type "gpedit.msc," and press Enter.
     
   • Navigate to Computer Configuration > Administrative Templates > System > Driver Installation.
     
   • Look for any settings related to driver installation or driver signing, and make sure they are set to "Not configured" or "Disabled."
     
   • Restart your computer and try to load the driver again.
     
4. Update or Reinstall the Driver: If the driver is outdated or corrupted, updating or reinstalling it may resolve the issue. Visit the manufacturer's website to download the latest version of the driver, or use Device Manager to update or reinstall the driver.
   

I'm trying to disable my antiviry temporarely now.

Could someone help me with this?

Thank you

BSOD while using the internet. error (L1C63x64.sys)


Hi trainman81,

Welcome to the 10forums.

Daemon tools, Alcohol 120% and Power Archiver Pro uses SCSI Pass Through Direct (SPTD), which is a well known cause for BSOD's.
Please remove Daemon Tools and run the SPTD pass through remover.

1. Uninstall Daemon Tools
2. Download the SPTD standalone installer and follow these steps:
   • Double click the executable to open it
   • Click on the button shown below

If the button is grayed out, like in the image, there is no more SPTD installation on your system, and you can close the window
