Unable To Load Process Monitor Device Driver

Unable To Load Process Monitor Device Driver

Delete the Process Monitor node or delete all the keys and values under the node. Before doing this you may want to make sure procmon is not running. Running procmon /terminate command is a good option to consider.

Sysinternals Process Monitor

Active3 years, 7 months ago

I am trying to load Process Monitor (Procmon.exe) from Sysinternals, and I get the following error on startup.

Unable to load Process Monitor device driver

In the Event Viewer, I get the following.

Driver PROCMON11.SYS has been blocked from loading.

What is blocking it from loading?

Background information: I have no anti-virus or malware checker software installed, other than Windows Defender (which I think is part of Windows 7).

It seems that most people on the web who had this problem, solved it by installing a newer version of procmon, or an older version if their's was the latest.

I was not aware that Procmon.exe even needed a 'PROCMON11.SYS'. I've been running Process Monitor as a standalone executable just fine. I searched my C drive for a procmon11.sys and it does not exist. Maybe it is packaged with the executable?

Viruses often try to prevent software from running that might alert someone to its presence. It sounds like a virus might be aware that you are trying to start Process Monitor and giving you this obscure error message to throw you off track.

Try installing the free version of AVG... or try installing Spybot Search and Destroy. If I'm right... the installation or update of those programs will probably fail.

An action that worked for me was to restart the computer (powering it off in the process, if it matters).

Platform:

  • Windows XP SP2 Professional 64-bit.
  • Process Monitor v3.03 (released 2012-07-16).
  • I had previously used Process Monitor v2.03 (likely release date 2008-12-10).

Evidently, Procmon requires the Workstation service running in order to start. It uses that service to enumerate something and will silently die without it.

This is not documented anywhere and is pretty bogus.

Try running ProcMon as administrator (right-click ProcMon.exe and select 'run as administrator').

Download Process Monitor 64 Bit

By default, it'll pop the 'Run as Administrator' dialog (probably triggered by trying to access a kernel-mode driver), but if you turned off UAC, you may not get that dialog, and th app would just fail in accessing the driver.
