Update the Product Key

To update your application to use a new trial key or a full version key. You only need to find the file dynamsoft.webtwain.config.js and replace the key in it

Dynamsoft.WebTwainEnv.ProductKey = '{the new key}';

For the full version, you also need to make sure that you have set the following

Dynamsoft.WebTwainEnv.Trial = false;

If you are using the trial version but doesn't have a valid key, you can request a trial key here.

If you can't find the file dynamsoft.webtwain.config.js, you might be using a file called dynamsoft.webtwain.min.js instead. In this case, you can simply write the following line in your own javascript code before using any APIs of the Dynamic Web TWAIN SDK.

Dynamsoft.WebTwainEnv.ProductKey = '{the new key}';

Decide On Required Licenses

Dynamic Web TWAIN is licensed on a per-Server per-Application basis and it comes in several different editions. To determine which licenses you need for your application, you basically need to be sure of the following. For more info, check out the License Agreement.

  1. What operating sytems and browsers your clients use.
  2. How many web servers (physical or virtual) will the application be deployed to.


It doesn't matter what operating system the server runs.
