If you are developing a web application, please follow the steps below to use Dynamic Web TWAIN:

1. Input Web Server License in Licensing Tool. More info
2. Run Lpk_tool.exe and generate DynamicWebTwain.lpk file. More info
3. Add DynamicWebTwain.lpk to your project.
4. In the HTML page, insert an <object> tag for the License Manager object before any other <object> tags. The License Manager is an ActiveX control that is installed with Internet Explorer.

<object classid = "clsid:5220cb21-c88d-11cf-b347-00aa00a28331" VIEWASTEXT>
<param name="LPKPath" value="DynamicWebTwain.lpk" />
</object>

Note: This classid, "5220cb21-c88d-11cf-b347-00aa00a28331", is for the License Manager and not for your ActiveX controls. You must use the same classid every time you refer to the LPK file. In addition, you should keep the Name parameter of the tag as "LPKPath", and set the Value parameter for the tag of the License Manager object to the LPK file name and path.

5. Add DynamicWebTWAIN.cab, which can be found in the installation folder of Dynamic Web TWAIN, to your project.

6. Insert a <object> tag for Dynamic Web TWAIN.
