.net - C# nuance omnipage OCR SDK Engine.SetLicenseKey() -

im using nuance omnipage ocr sdk.

while compiling got error: engine initialization error, or no appropriate license. found should use engine.setlicensekey() method.

what file , license key should provide engine.setlicensekey()?

    try     {         list<ocr_error> ocrerrors = new list<ocr_error>();         system.console.write("** title: nuance capture development system csharp sample01 application **\n");         system.console.write("initializing engine -- engine.init\n");         engine.setlicensekey("licensefile.lcx", "licensekey");         engine.init("companyname", "projectname");         if (engine.recerr == recerr.api_init_warn)         {             ocrerrors.add(new ocr_error()             {                 message = "module initialization warning. 1 or more recognition modules haven't been initialized properly.",                 innermessage = "for more information, see engine.modulesinfo"             });             return;         }         string inputfilename = @"d:\3141864.pdf";         string inputfilepath = path.getfullpath(inputfilename);         string outputfilepath = inputfilepath.replace('.', '_') + @".pdf";         if (file.exists(outputfilepath))             file.delete(outputfilepath);         file.create(outputfilepath);          using (settingcollection settings = new settingcollection())         {             using (document doc = new document(inputfilepath))             {                 int sourcepagescount = doc.pagecount;                 (int = 0; < sourcepagescount; i++)                 {                     using (page page = new page(inputfilepath, i, settings))                     {                         page.preprocess();                         page.recognize();                         using (document oputputdocument = new document(outputfilepath, 0, settings))                         {                             oputputdocument.insertpage(page, i);                             oputputdocument.save(outputfilepath);                         }                     }                 }             }         }     }     catch (exception e)     {         system.console.write(e.message);//error: license manager error.     }         {         system.console.write("free resources allocated engine -- engine.forcequit\n");         engine.forcequit();         system.console.write("end of sample01 application\n");         system.console.readkey();     } 

if bought software should come proper documentation and/or support how load license file , key in code. check docs or contact them.

if didn't buy software, seems requires valid license file , key. might need purchase license.

if bought software without documentation , support, consider money lost.
