Understanding ES3 Issues


Typical ES3 Opening Challenges

Missing e-Szigno

When you double-click your ES3 file, you may see a dialog box from your operating system stating that it "Cannot Open This File Type". When this happens, it is commonly due to e-Szigno missing in %%os%%. Your operating system cannot associate your ES3 with e-Szigno, so double-clicking the file won't work.


Tip: Another ES3-related program can be selected to open the file by clicking "Show Apps" and finding the application.


Incorrect e-Szigno Version

Your E-Szigno Signed Document file is incompatible with e-Szigno because you might have the wrong version installed. Visit the Microsec Software Engineering & Consulting Plc. website to download (or purchase) the latest version of e-Szigno. This problem is predominately due to having a E-Szigno Signed Document file version that was created by a newer version of e-Szigno than what you have installed on your PC.


Tip: You can sometimes get hints about the right program version by right-clicking on the ES3 file, selecting "Properties", and looking at the version information.


Conclusion: The majority of ES3 file opening issues are due to not having the correct e-Szigno version installed.


Other ES3 File Opening Causes

In the majority of cases, installing the right version of e-Szigno will resolve your issue. There can be other issues - unrelated to software - preventing you from opening ES3 files. These issues include:

  • ES3 file references in the Windows Registry are broken
  • Unintentional removal of the description of the ES3 file inside the Windows Registry
  • Corrupt install of e-Szigno or other ES3-related program
  • Something has caused file corruption of your ES3
  • The ES3 is infected with a virus
  • ES3-related hardware has device drivers that obsolete
  • Your computer does not have the adequate system resources to open the E-Szigno Signed Document format
