[SOLVED] My program crashes when is running in a PC that hasn't Qt installed

[qt_developer]

Hi all,

My program crashes when is running in a PC that hasn't Qt installed.

I have added the libraries QtXml4.dll and QtXmlPatterns4.dll in the same place that the executable file.

The code that closes the program:

QXmlInputSource source;
source.setData(data);
 
QXmlSimpleReader reader;
reader.setContentHandler(&qxmlDefaultHandler);
 
bool parsed = reader.parse(source); // The program crashes in this line

QXmlInputSource source;
source.setData(data);

QXmlSimpleReader reader;
reader.setContentHandler(&qxmlDefaultHandler);

bool parsed = reader.parse(source); // The program crashes in this line

To copy to clipboard, switch view to plain text mode 

If I execute the program in the development PC, the application works properly.

What's wrong?

Regards.
