If you think that the utilities are useful and you want to say thanks for making support of future development, you are welcomed to donate some money. We had to find some money to buy a house digital signature.


Portable open source tool which can help by translating error codes into a more meaningful text description. The interface is simple - just a box to type your code, and another which displays the details - so there doesn’t seem much to learn.

The program also supports a wide range of codes: regular Windows errors, DirectX, NTSTATUS errors, Windows Internet errors, STOP codes, And we think it can probably be configured to read more (Settings > System modules), although there’s no documentation to confirm that and we didn’t test it.

The lightweight application is less than a megabyte, and it is compatible with Windows XP SP3 and higher operating systems. You can download either the installer or portable version.


To activate portable mode, create "errorlookup.ini" in application folder, or move it from "%APPDATA%\Henry++\Error Lookup".
