重新连接到Excel工作簿时发生OLEDB AccessViolationException异常

我目前正在使用UiPath（Visual Basic）自动化流程。 过程的一部分使用大型excel文件，因此我使用OLEDB和SQL与它们交互

在我个人的VDI上测试没有问题，但是在Azure VM上部署时，我的OLEDB连接出现问题

第一次使用OLEDB连接到Excel工作簿是可行的，但在断开连接并处理后，如果尝试重新连接到同一Excel工作簿，则会出现AccessViolationExceptions

谢谢大家

此错误与windows系统体系结构、系统32和64有关。当系统创建OleDb实例时，他调用MSCorlib，它位于不同的目录中，x（86）等等。

Hmm，我遇到了相同的问题（这是新的行为）。你解决过这个问题吗？

Provider=Microsoft.ACE.OLEDB.12.0;Data Source= {0};Extended Properties='Excel 12.0 Xml;HDR=YES;Readonly=False;IMEX=1';
