Getting Started > Upgrading SmartZone OCR > Upgrading from SmartZone OCR 6 to SmartZone OCR 7

This section describes how to upgrade from SmartZone 6 to SmartZone 7. While generally you'll be able to replace SmartZone 6 with SmartZone 7, there are a few important changes you may need to consider.

Nuget Package Changes

Since SmartZone now supports both Windows and Linux, some changes have been made to dependencies on platform specific OCR Runtime NuGet packages.

These changes were made so that Accusoft.SmartZone.Net is a quick-start package which includes all you need on any Operating System, while Accusoft.SmartZoneOCR.Net now gives you control of which platform specific runtime to include. For more information, see NuGet Packages.

Assembly Changes

Some native libraries that were previously integrated in the Accusoft.SmartZoneOCR.Net assembly are now included as separate dlls. These libraries will be extracted to the same directory as the assembly when using the Nuget Package. For Windows the libraries are named Accusoft.SmartZoneOCR.Common.dll and Accusoft.SmartZoneOCR.Common64.dll. For Linux distributions, the name of the file is These need to be included when redistributing any application that uses the SmartZoneOCR SDK.

API Changes

The class Accusoft.SmartZoneOCRSdk.SmartZoneException now derives from System.Exception instead of System.ApplicationException. Applications that explicitly catch System.ApplicationException to handle SmartZone exceptions will need updating.

Unsupported characters have been removed from all predefined character sets in the CharacterSet class. The following characters are no longer present in any predefined character set: ^`|~¡¦¨ª¬¯±²³´µ¶¸¹º¼½¾×÷ƒˆ˜–—‘’‚“”†‡…‰‹› as well as the DELETE (\u007f) and NO-BREAK SPACE (\u00a0) characters. Apps can edit and define character sets to add characters not presently included for that language with some restrictions.

If you encounter any porting issues, please contact Support for assistance.
