What are vmnetAdapter.sys Error Messages?

vmnetAdapter.sys Blue Screen of Death (BSOD) Errors

There are a number of reasons why you could be encountering issues with vmnetAdapter.sys. Most of the issues concerning sys files involve Blue Screen of Death (BSOD) errors. These types of vmnetAdapter.sys errors can be cause by hardware problems, outdated firmware, corrupt drivers, or other software-related (eg. VMWare Workstation Player update) issues. Some of these errors include:

vmnetAdapter.sys could not be found.
vmnetAdapter.sys failed to load.
The file vmnetAdapter.sys is missing or corrupt.
Windows failed to start - vmnetAdapter.sys.

A problem has been detected and Windows has been shut down to prevent damage to your computer. The problem seems to be caused by the following file: vmnetAdapter.sys.

:( Your PC ran into a problem that it couldn't handle, and now needs to restart. You can search for the error online: [BSOD] (vmnetAdapter.sys).

STOP 0x0000003B: SYSTEM SERVICE EXCEPTION (vmnetAdapter.sys) STOP 0x00000050: PAGE FAULT IN A NONPAGED AREA (vmnetAdapter.sys) STOP 0x0000000A: IRQL NOT LESS EQUAL (vmnetAdapter.sys) STOP 0x0000007E: SYSTEM THREAD EXCEPTION NOT HANDLED (vmnetAdapter.sys) STOP 0x0000001E: KMODE EXCEPTION NOT HANDLED (vmnetAdapter.sys) STOP 0×0000007A: KERNEL DATA INPAGE (vmnetAdapter.sys)

It's Critical to Resolve Blue Screen of Death Errors

In the majority of cases, you will encounter vmnetAdapter.sys BSOD errors after you've installed new hardware, software (VMWare Workstation Player), or performed a failed Windows Update. In other cases, software corruption caused by a malware infection can lead to vmnetAdapter.sys Blue Screen of Death errors. Therefore, it's critical to make sure your anti-virus is kept up-to-date and scanning regularly.

GEEK TIP : As a rule of thumb, it's always a good idea to create a Windows "Snapshot" backup / System Restore Point before making any hardware or software changes to your computer. That way, it's very easy to restore your system in the unfortunate event you encounter a vmnetAdapter.sys Blue Screen of Death error after recent changes.

How to Fix vmnetAdapter.sys Errors in 3 Steps (Time to complete: ~5-15 minutes)

If you're encountering one of the error messages above, follow these troubleshooting steps to resolve your vmnetAdapter.sys issue. These troubleshooting steps are listed in the recommended order of execution.

Step 1: Restore your PC back to the latest restore point, "snapshot", or backup image before error occurred.

To begin System Restore (Windows XP, Vista, 7, 8, and 10):

Hit the Windows Start button
When you see the search box, type "System Restore" and press "ENTER".
In the search results, find and click System Restore.
Please enter the administrator password (if applicable / prompted).
Follow the steps in the System Restore Wizard to choose a relevant restore point.
Restore your computer to that backup image.

If the Step 1 fails to resolve the vmnetAdapter.sys error, please proceed to the Step 2 below.

Step 2: If recently installed VMWare Workstation Player (or related software), uninstall then try reinstalling VMWare Workstation Player software.

Step 3: Perform a Windows Update.

When the first two steps haven't solved your issue, it might be a good idea to run Windows Update. Many vmnetAdapter.sys error messages that are encountered can be contributed to an outdated Windows Operating System. To run Windows Update, please follow these easy steps:

Hit the Windows Start button
In the search box, type "Update" and press "ENTER".

Windows 10: C:\Windows\System32\drivers\
Windows 10: C:\Program Files (x86)\VMware\VMware Player\
Show 1 more directory +

Download vmnetAdapter.sys Files (Malware-Tested 100% Clean)

CAUTION : We strongly advise against downloading and copying vmnetAdapter.sys to your appropriate Windows system directory. VMware typically does not release VMWare Workstation Player SYS files for download because they are bundled together inside of a software installer. The installer's task is to ensure that all correct verifications have been made before installing and placing vmnetAdapter.sys and all other SYS files for VMWare Workstation Player. An incorrectly installed SYS file may create system instability and could cause your program or operating system to stop functioning altogether. Proceed with caution.
