# Silent Installation(for Update)

Silent installation is available for updating.
Silent installation displays no dialog box during installation. User intervention is not required during the installation.
This helps you install the product on many PCs at a time.

## Settings and Installation (for Update)

Run “Setup.exe” in the “dwdiup {version}” folder of the downloaded update installer via the command line or a batch file as follows:
setup.exe /s

## Checking Installation Results

The following is how to check the result of a silent installation:
Procedure
1.
After the installation is complete, execute the following command at the command prompt:

2.
Then, execute the following command:
echo %errorlevel%
When “0” is displayed, the installation is successfully completed. For other exit codes, see “Exit Codes".

### Checking the Installation Log “DWDocInfoEntrySetup.log”

Installation logs are stored in the following location.

Log Type | Folder | Files
--- | --- | ---
Installation log | {System Drive}:\Users\{username} \App Data\Local\Temp\DWDocInfoEntrySetup{YYYYYMMDD} Where {YYYYYMMDD} is the date of installation. | Setup.exe logs DWDocInfoEntrySetup.log Installer logs dwdi{version}jpn.log

In DWDocInfoEntrySetup.log, find the line that records "DWDISetup.exe" and "is done". The "N" part of "(ExitCode:N)" recorded at the right end of the line is the exit code.
When “0” is recorded, the installation is successfully completed. For other exit codes, see “Exit Codes".
