VNLCopyFileToSystemDir: Failed to copy file: “C: Windows system32 drivers hcmon.sys”. (null) 32 VNLInstallHcmon: Failed to create service for hcmon driver. This looked like that there are not sufficient permissions to copy the hcmon.sys to the destination folder, although the installer told me that he is using elevated permissions. FAILED TO INSTALL THE HCMON DRIVER - Josh on May 26, at 2: That was my problem Reply. You may not have to try them all. Failed to handle bit properly Leave a reply Cancel reply Your email. These warnings appear to be caused by hcmon.sys which is used by VMware Player to detect USB ports becoming active. Sounds like you use USB 3 which is not supported on Windows hosts. Based on my search, you could go into services and disabled vmware usb arbitration service then you could test vmware to see if it still works. Enable HCMON by creating a EnableHCMON registry value (DWORD 32 change type, from 0 to Data 1) in HKEYLOCALMACHINE SYSTEM CurrentControlSet Services SK Parameters. Reboot the computer (required) Install VMWare View Client. After the successful installation, Disable HCMON by deleting the EnableHCMON registry entry.

I was installing VMware Workstation 12 Pro yesterday and I kept getting this “Failed to install hcmon driver” error at the very end of the install, and each time it would undo the install and I’d be left with nothing.
After a few Google searches I found this page in the VMware Knowledge Base and learned the problem was pretty stupid, but easy to fix.
See, I also manage a 32-core 128gb ram server running VMware ESXi 6 in my office and in order to connect to that VMware host I use the VMWare vSphere client. Apparently the vSphere client conflicts with the VMware Workstation installation so I had to uninstall it.
After removing the vSphere client I no longer got the “Failed to install hcmon driver” error while installing VMware Workstation 12.

Once I installed Workstation, the vSphere Client reinstalled perfectly fine.

Also, remember to restart your machine after installs and uninstalls to avoid other issues that can arise from not restarting!
