QT调用Adobe Reader 的com组件展示pdf，出现running错误

Question

错误提示：there is a problem with adobe acrobat/reader if it is running please exit and try again(103:103).
QT调用代码如下：

QAxWidget *m_pPDFwidget;
m_pPDFwidget = new QAxWidget("Microsoft Web Browser");
QString strFilePath = "C:\1.pdf";
m_pPDFwidget->dynamicCall("Navigate(const QString&)", strFilePath );

采取方法：
打开 adobe reader ，点击 Edit->Preferences->Security(Enhanced) 去掉 Enable Protected Mode at startup ，仍然有问题。

Answer 1

QString strFilePath = "C:\1.pdf";
->
QString strFilePath = "C:\\1.pdf";
