Support Request: SiteKiosk - Chrome engine - getting plugin to work like it did in IE


With IE officially being deprecated, we are moving to the chrome engine in SiteKiosk and have encountered a roadblock that requires your expert input.

The web application that we are showing uses a plugin (fingerprint reader WEB-key products from BIO-key). I can't seem to get it working in Chrome (it was/is working fine with the IE engine).

After increasing the logging, reviewing the log file and finding the exception, I have edited the config file as outlined in a previous support request ( to include:

<scheme name="blob" desc="blob protocol" allowed="true" />

That moved it forward, but now i am getting a "ERR_UNKNOWN_URL_SCHEME" when the plugin is called. I saw this support post (, but after editing the config again to include:

<schemes defaultallowed="true">

It still doesn't seem to allow the plugin to fire correctly.

Can you please point me to the next step i should look at?

Thank you.

Thank you for your inquiry. When it comes to plugins, you cannot add them or incorporate them in Chrome Browser as you would a regular browser. You can include the JavaScript code for the plugin here to test and see:
