ET3 File Complications


Common Problems Opening ET3 Files

Missing e-Szigno

When trying to open your ET3 file, you get the error "Can't Open ET3 File Type". When this happens, it is commonly due to e-Szigno missing in %%os%%. This will prevent you from double-clicking to open the ET3 file because the OS doesn’t know how to handle it.


Tip: If you have another software that you know opens ET3 files, you can select it by hitting the "Show Apps" button.


Incorrect e-Szigno Version

Sometimes your installed version of e-Szigno won't support your E-Szigno Recorded Delivery Data file. You will need to download a newer version of e-Szigno if you don't have the right version. The primary cause of this problem is that your E-Szigno Recorded Delivery Data file was created by a different (newer) version of e-Szigno than what's installed.


Tip: Find clues on the correct software version by right-clicking your ET3 file and clicking "Properties".


Conclusion: The majority of ET3 file opening issues are due to not having the correct e-Szigno version installed.


Additional ET3 Opening Issues

Although you might already have e-Szigno or another ET3-associated software installed on your computer, you can still encounter problems opening E-Szigno Recorded Delivery Data files. If you are still having problems opening ET3 files, there may be other issues that are preventing you from opening these files. Problems unrelated to software:

  • ET3 file type Registry entries are wrong
  • Unintentional removal of the description of the ET3 file inside the Windows Registry
  • Defective install of a ET3 program, such as e-Szigno
  • ET3 file corruption
  • Your ET3 is infected with malware
  • Device drivers for ET3-related hardware are out-of-date
  • Windows cannot load your E-Szigno Recorded Delivery Data file due to insufficient resources (eg. RAM)

Poll: How many different computer files (eg. documents, videos, audio) do you typically view or edit on a daily basis?
