I get that error message when I try to encrypt a freshly created Windows 10 virtual machine. 

  • VM is shutdown before each attempt.
  • It doesn't matter if I encrypt all files or just the TPM-related files.
  • Tried al sorts of secure passwords.
  • Ran chkdisk on host HD. Also verified NTFS disk-access credentials for folder/files for the VM. I removed file/folder compression from the host, too.
  • VM Workstation 17.6.2 build-24409262 downloaded and installed yesterday
  • Windows 10 22h2 64-bit ISO created from windows media creation tool, also downloaded yesterday
  • Host is running Windows 8.1 64-bit
  • I had taken a snapshot of the VM prior to my first attempt, but deleted the snapshot after getting the warning that it needed to be deleted before encryption.
  • Restarted the VM then shutdown it down after snapshot was removed
  • Restarted workstation
  • Virtual disk current size: 10.8 GB
  • Virtual Disk Max size 100GB
  • Space left on host disk: 673.4 GB

Hope someone can tell me how to proceed, I'm out of ideas.

Thanks in advance.
