When adding these codes into the project.
Qt Code: 
  1. QAxWidget *wordActive = new QAxWidget(0,0);
  2. wordActive->setControl(QString::fromUtf8("{00020906-0000-0000-C000-000000000046}"));
To copy to clipboard, switch view to plain text mode 
First is normal .Then there is the error.I don't know why.I do not have a commercial lisience.So does it matter.And what's the reason called these errors?
CoCreateInstance failure (????????????é¡£)
QAxBase::setControl: requested control {00020906-0000-0000-C000-000000000046} could not be instantiated
By the way .I use the QApplication ,not the QCoreApplication.
