Our office purchased KuTools for Excel on 17 September 2021. Recently our IT department at Mississippi State University moved me to a new PC tower. Unfortunately now my KuTools doesn’t work in the new system. When I select any option from the toolbar my Excel Spreadsheet closes the document. When reopening the document I receive this error, "The file format and extension of 'Loading" don't match. This file could be corrupted or unsafe. Unless you trust its source, don't open it. Do you want to open it anyway." After opening KuTools still doesn't work. I was sent an update link with the instructions to uninstall an install link. Once I uninstalled, I shut the system down and reopened. I then downloaded the link, reinstalled, and rebooted. Unfortunately, I am still experiencing the same error as in my first email. Do you have any suggestions?

我们的办公室于 17 年 2021 月 XNUMX 日购买了 KuTools for Excel。最近，我们密西西比州立大学的 IT 部门将我搬到了一座新的电脑塔。

不幸的是，现在我的 KuTools 无法在新系统中运行。

当我从工具栏中选择任何选项时，我的 Excel 电子表格将关闭文档。

重新打开文档时，我收到此错误，“正在加载的文件格式和扩展名不匹配。此文件可能已损坏或不安全。除非你相信它的来源，否则不要打开它。还是要打开。”

打开 KuTools 后还是不行。我收到了一个更新链接，其中包含卸载安装链接的说明。

卸载后，我关闭系统并重新打开。

然后我下载了链接，重新安装并重新启动。

不幸的是，我仍然遇到与第一封电子邮件相同的错误。

你有什么建议吗？
