Symptoms: The following appears in the setup error log: Code: 2016-08-03 13:38:34, Error SP SPMountWIMCallback: Error mounting/unmouting C:\$WINDOWS.~BT\Sources\SafeOS\SafeOS.Mount\windows\winsxs\amd64_microsoft-windows-servicingstack_31bf3856ad364e35_10.0.14393.0_none_36d3ccc3ddfd1ecb\CbsMsg.dll. GLE [gle=0x00000057] 2016-08-03 13:38:44, Error SP CMountWIM::DoExecute: Failed to mount WIM file C:\$WINDOWS.~BT\Sources\SafeOS\winre.wim. Error 0x80070057[gle=0x00000057] 2016-08-03 13:38:44, Error SP Operation failed: Mount WIM file C:\$WINDOWS.~BT\Sources\SafeOS\winre.wim, index 1 to C:\$WINDOWS.~BT\Sources\SafeOS\SafeOS.Mount. Error: 0x80070057[gle=0x000000b7] 2016-08-03 13:38:44, Error MOUPG MoSetupPlatform: ExecuteCurrentOperations reported failure! 2016-08-03 13:38:44, Error MOUPG MoSetupPlatform: Using action error code: [0x80070057] 2016-08-03 13:38:44, Error MOUPG CDlpActionImageDeploy::ExecuteRoutine(403): Result = 0x80070057 Description: As indicated in the log, the problem is caused by the system failing to mount the WIM file. This can be confirmed by attempting to mount a WIM file using the command line. Code: DISM.exe /Mount-Image /ImageFile:somefile.wim /Index:1 /MountDir:C:\Temp /ReadOnly This will result in the error Code 87, and the DISM log will indicate Invalid Parameter, which is error code 0x80070057. This has been observed when a filter driver is interfering with the SetFileSize call. Check the loaded filter drivers with the command: Code: fltmc filters The list may contain cbfltfs4 (which is cbfltfs4.sys), a virtual disk image redirection filter driver or something similar. Solution: Disable third party filter drivers and attempt the upgrade again.
