How to silently install/uninstall Dynamic Web TWAIN via Command Line

To silently install Dynamic Web TWAIN via Command Line, you need at least one of the MSI installers to be installed.

Please run the CMD as administrator, and enter the following line of code with the relevant MSI name.

C:\Users\{User}\{DWT Path}>msiexec /i WebTwainMSITrialX86.msi /quiet

To silently uninstall Dynamic Web TWAIN, you can replace the /i parameter with /x.

C:\Users\{User}\{DWT Path}>msiexec /x WebTwainMSITrialX86.msi /quiet

If you want to create an install/uninstall log, you can use a command line which looks like this:

C:\Users\{User}\{DWT Path}>msiexec /x WebTwainMSITrialX86.msi /quiet /L*V "C:\log\example.log"

For Web TWAIN v12.0 and later, the MSI files are put in the installation path at C:\Program Files (x86)\Dynamsoft\Dynamic Web TWAIN SDK {Version No.} {Trial}\Resources\MSI.

For Web TWAIN v11 and earlier, the MSI installers are not available in the installation directory. Please contact us for the trial or full version download link.

Note: if you are a system administrator, you can also use the MSI to remotely deploy the scan service to all the end-user machines. Please refer to
