You may experience Windows PE download errors if your PC is behind a SonicWALL Firewall.
Example error in the Reflect download manager (ReflectDL.exe) log:
Download file: winpe.wim from set: pe3x64wim To: C:\Users\<USER>\AppData\Local\Temp\Installer\Macrium\Windows AIK\Tools\PETools\amd64\winpe.wim INFO: Http Status : 200 File system supports sparse files Download successful Downloaded file 'winpe.wim' failed MD5 check.
You may experience this problem if a computer is behind a firewall or behind a proxy server. This problem occurs if one of the following conditions is true:
- The proxy server environment does not support the HTTP 1.1 range request feature.
- You are behind a SonicWALL firewall device, and the "Enable HTTP Byte-Range request with Gateway AV" is not enabled.
Enable HTTP Byte-Range request
For more information see the following SonicWALL support articles:.
|Note: If download problems continue after enabling 'HTTP Byte-Range request' then completely disable SonicWALL for the duration of the download|
