Prerequisites:

- Retrieve files vmss2core.exe and zlib1.dll from VMware workstation installation folder

C:\Program Files (x86)\VMware\VMware Workstation or C:\Program Files\VMware\VMware Workstation\


Note: If vmss2core is not available in these install directories, it can be downloaded. Download location is available in https://kb.vmware.com/s/article/2003941


Download VMSS2CORE Tool: https://flings.vmware.com/vmss2core

Steps:

- Place the vmss2core tool and the VMware snapshot file into the same folder

- Run the vmss2core (vmss2core-sb-8456865.exe in this example) in the command line with the following parameters:


Specify the guest operating system from which the snapshot was created:

* W8 - Windows 8 and later or Windows Server 2012 and later.

* W - Windows 7 and older or Windows Server 2008 and older.


- Virtual machine snapshot filename (for example, virtual_machine_name.vmsn)

Sample Command: vmss2core-sb-8456865.exe -W8 "virtual_machine_name.vmss virtual_machine_name.vmem"


Note: When the vmss2core tool completes the operation, it creates a memory dump file named memory.dmp that can be used for additional troubleshooting ( Please share this to MS Support )
