Microsoft Office Excel cannot access the file, There are several possible reasons

今天在做EXCEL打印读取模板时报错了，错误信息如下：

Microsoft Excel cannot access the file 'D:xx.xlsx'. There are several possible reasons:

• The file name or path does not exist.
• The file is being used by another program.
• The workbook you are trying to save has the same name as a currently open workbook

网上解决方法一大片各种各样，下面这篇博客的方法解决了我的问题，其中提到了两点，但我仅操作第一步后便解决了问题，我的系统环境是Server2012R2,office装的是2013。
