Hello. Any fixes for my issues in new 3.5.0 release? should I update and try?

Another new crash from your library. Please check attached ZIP and let me know when it can be fixed.

Is it the right topic where i can post issues? Because i don’t see our problems reported far ago solved


Hi Egormarkov,

Thank you for coming back.

We are sorry for the inconvenience, we have investigated on your shared PDF document and during investigation we found that your file is password protected and without password in conversion process it is generating exception and may be this the reason for server crash. kindly try to convert the same file with password and share its password with us for further investigation, here is the sample code for password protected files conversion.

public static void ConvertToWordDocumentAdvanceOptions()
// Instantiating the conversion handler from custom common class
ConversionHandler conversionHandler = Common.getConversionHandler();

//Set password to unprotect protected document during loading
LoadOptions loadOptions = new LoadOptions { Password = “secret” };

// convert file to Doc, starting from page 2 and convert 2 pages,
SaveOptions saveOptions = new WordsSaveOptions
ConvertFileType = WordsSaveOptions.WordsFileType.Doc,
PageNumber = 2,
NumPagesToConvert = 2,


kindly note that your previously raised all issues are fixed and you can check status of issue on first page of this thread where issue number and status are mentioned.

If you will need any help or you will have any other questions please feel free to ask.

Warm Regards,



Thanks for your response.

Few questions:
1. If PDF app can show this file - it doesn’t mean that your app can convert to HTML, right?
2. Anyway, your app should catch any exception and not crash the server - because it crash - it stops Application Pool and our users having troubles to connect. Please raise an issue to dev team


Hi Egormarkov,

Thank you for the inquiry.

In case of PDF with password protected you can not convert it to any other format without inserting password, for this purpose you need to handle the such scenario in your code for now, regarding handling of these exception at API level, we will forward it to our product team. Once we get any update from them we will contact you here.

Thank you for your cooperation.

Warm Regards,


No, this type of exception cannot be catched from our codes. we have global try catch block, but it cannot catch this one.


Hello Egormarkov,

Thank you for the details and clarification we have moved your raised point to the product team. after getting response from product team we will update you here.

Thank you for your patience.

Hello Egormarkov,

We are further investigating your issue as per provided event logs. During investigation we have found that exceptions are caught in our try catch block. please have look on this screenshot for more details. For further investigation on this issue we need your sample code to know how you are applying global try catch, this information would be very helpful to regenerate the scenario at our end.

Thank you for your cooperation.

Warm Regards,
