Common SDO Opening Problems

Signere.no Document Viewer Not Present

If you attempt to load your SDO file, you experience a message such as "Can't Open SDO Files". Customarily, this means that Signere.no Document Viewer is not installed on %%os%%. The typical path of opening your SDO with a double-click won't work because %%os%% cannot make the program connection.


Tip: If you know of another program that can open your SDO file, you can try opening it by selecting the application from the programs listed.

Occasionally, you might have an outdated version of Signere.no Document Viewer installed that's incompatible with your Signed Document type. Visit the Signere.no website to download (or purchase) the latest version of Signere.no Document Viewer.
