Hello,

Enable HCMON by creating a EnableHCMON registry value (DWORD type, Data 1) in HKEYLOCALMACHINE SYSTEM CurrentControlSet Services SK Parameters. Reboot the endpoint. Install VMWare View Client. Disable HCMON by removing the EnableHCMON registry value. To resolve this issue, manually remove the hcmon.sys driver from your server. To manually remove the hcmon.sys driver from the server: Right-click My Computer and click Manage. Click Device Manager. Click View Show hidden devices. Double-click Non-Plug and Play Drivers. Right-click VMware hcmon and click Uninstall.

This seems to be my last resort in solving this problem, I hope someone has had this issue before and can provide a new direction into solving this.

Scenario: had an upgrade from 6.7 U1 to 6.7 U3, so took the time to install the latest remote console software (worked fine).

I couldn't establish a session to my VM's anymore (due to an SSL issue).

In trying to understand and solve that issue, I uninstalled my vmware software (as far as I remember, only the remote console was installed).

Ever since, I'm unable to reinstall the software.

This is the error:

Failed to install the hcmon driver

Now I've come across several simple things that should help me, but it didn't:

• remove vsphere client, install remote console and reinstall vsphere client
• install with extra admin priviliges
• Do a register workaround (enable HCmon, install, remove regkey)
• …

I was unfamiliar with the hcmon.sys file before this issue started. From what I learned, this should be provided by the OS under the System32 < drivers folder.

It seems this one is missing on my device, but I'm unsure if it should be there (I also read a hcmon.sys file is being installed through the remote console installation).

To be sure, I've cleaned up the registry (ccleaner) and ran a sfc /scannow, which succeeded without errors.

If anyone has any other recommendation, I'd be open to it.
