When trying to deploy Windows 11 using the Install Windows OS option we get an error saying that the PC does not meet the minimum system requirements to install this version of windows. 

When we install that same windows ISO using a flash drive it works fine.


Release: Deployment Solution 8.6 and 8.5 RU4

Component: Winpe11


When performing OS install a tpm check is needed but the tpm.dll file is missing from the automation environment:

from c:\windows\system32\sysprep\panther\setupact.txt file will have: 

Error                        VerifyTPMSupported:TBS.dll not found.[gle=0x0000007e]



  1. Locate the tpm.dll file for a windows 11 production environment.  The path of the file is located at:
  2. Locate the boot.wim file of your preboot configuration
  3. Go to server where NetBoot Services is installed to: 
    <install drive>:\Program Files\Altiris\Altiris Agent\Agents\Deployment\SBS\Images\<Preboot Configuration>\x64\sources\boot.wim
  4. Create a directory for the mount ( ex: c:\temp):
    mkdir c:\temp
  5. Run a dism command to mount the boot.wim file
  6. Open command then cd to boot.wim directory
  7. From command enter:
    DISM /Mount-Wim /WimFile:"boot.wim" /index:1 /MountDir:"c:\temp"
  8. cd:
  9. Copy the tbs.dll file to windows\system32\
  10. Run:
    DISM /unmount-wim /MountDir:"c:\temp" /commit
  11. If you have multiple site servers then copy the boot.wim file to each of the same directories
