When building boot environment, Error -1803 occurs and creating boot environment fails

Details

Error -1803 may cause the creation of a boot environment to fail.

Causes

We confirmed this issue occurs under the following conditions:

• Insufficient space in the DISM temporary file.
• The temporary file "AIP_WIM_MOUNT_TEMP_XXXXXXXX_XXXXXX" is open in Explorer or interfered with by antivirus software.

We will post an article if other factors are identified.

Workaround

1) Ensure there is at least 5GB of free space in the DISM temporary file. Use GetTempPathA to find the temporary file directory path. To increase available space, edit the Windows environment variable.

%USERPROFILE%\AppData\Local\Temp

2) Please do not access the DSM temporary file.

If this issue occurs, and the DISM temporary file remains in a "failed" state, you will need to delete the DISM temporary file manually.
