最近在用M1芯片的MacBook pro安装visio的时候提示：

Setup can't find or validate an installation file. Please try reinstall Office from your installation source, or if you install from a downloaded package,please re-install. if you continue to have problems,please contact Microsoft or your system adminstrator.

一开始以为是版本的问题，因为据说目前的ARM 版Windows无法安装64位的程序。所以我测试了多款VISIO，不过都没啥用。

最后才发现，原来不能直接在ISO文件中安装，而是需要把里面的文件都复制出来，然后再安装就可以了。
