Hello, I need help.  I've upgraded to Workstation Pro 17.6.3 (Win 11, 24H2), but the installation caused BSOD with Stop code: THEAD EXCEPTION NOT HANDLED for driver hcmon.sys. 

Now, I cannot start a VM anymore because msg "VMWare Authorization Service isn't running".   When I try to start that service I get "Error 1075: The dependency service does not exist or has been marked for deletion.".  Even though the dependencies are running.

I've attempted to install 17.6.2, and even rollback to 17.5.2, but the installation process always crashes the kernel with the same exception.

I've tried removing hcmon.sys from C:\Windows\system32\drivers, reboot, install.  But the crash repeats.

I've analyzed the crash dump, but nothing useful is returned:

Crash Analysis: SYSTEM_THREAD_EXCEPTION_NOT_HANDLED (0x7E)

This blue screen (BSOD) error was caused by an access violation (0xC0000005) in hcmon.sys.
The crash occurred while attempting to read from an invalid memory address (0x00000028).

I've verified I have all my drivers are updated, and "sfc /scannow" found no corruption.

I had Hyper-V enabled, I've disabled it, and disabled the feature, but the crash continues.

I've tried disabling all anti-virus software, and even tried unplugging all USB devices.   I tried safe mode but installation will not allow to run in safe mode.

I've also tried a different user profile.

At this point, I'm considering a complete windows re-install.   

I'm 12hours into debugging this issue.  A lot of pain for updating VMWare Workstation Pro to the latest version. 

Any help is always appreciated 😀

Dhairya Tomar, this doesn't work.  After following your instructions, reboot, and install WS Pro, still get BSOD with same hcmon.sys error.  Minidump looks the same.
