Mine Type

The eSO Setup sets a Mine Type (Link Handler) to the SOSigOffice.exe to start eSO with a Link. The URL is eso:// and it can also contain all the StartParameter of the SOSigOffice.exe. To seperate the Parameter a | must be used.

This is working in Offline Application and in the Main Browsers (IE, Firefox, Chrome, Safari, Opera), in most of them the User gets a Warning/Message which he needs to accept.




To use that we add the following Registry Entry.


Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso] @="URL:eso protocol" "URL Protocol"=""




[HKEY_LOCAL_MACHINE\SOFTWARE\Classes\eso\shell\Open\Command] @="\"C:\\Programme\\StepOver\\eSignatureOffice\\SOSigOffice.exe\" \"%1\""


additional Setting for Chrome:

Open "Preferences" of Chrome, you can find it under %LOCALAPPDATA%\Google\Chrome\User Data\Default\Preferences

  1. Close Google Chrome.

  2. Open the Preferences file and search for excluded_schemes in protocol_handler.

  3. Add the line

    "eso": false,

    to excluded_schemes.

  4. Restart Google Chrome.
