Upgrade Win 10 can not open the Office 2013 file solution

Many Win7 users after upgrading to the official version of Win10, found that the original file created using Office 2013 can not be opened, including Word, Excel and PowerPoint. When trying to open these three types of files, the following prompts appear (from English translation, may be different from the Chinese version of the copy):

· Word: An error occurred while trying to open the file.
·Excel: There is a problem with this file and it cannot be opened.
· PowerPoint has three cases:
1 The application cannot start correctly
2PowerPoint found that <file name> There is a problem
3 Sorry, PowerPoint cannot read <file name>< Br> In fact, this kind of problem has nothing to do with the file itself to be opened. It is just that after Office 2013 arrives at Windows10, there is some “consistency”, and compatibility problems occur, which may not work properly.
Let's take a look at two solutions for not being able to open Office 2013 files after upgrading Windows 10:
1. Use the Office 2013 CD or ISO image to repair and install existing software. After opening the CD (or image), double-click the setup.exe installer to fix it.

▲Double-click setup.exe to run the Office 2013 installer
2. If there is no CD or image, you can enter the command in the “Command Prompt” command, as follows:
1 in Cortana Enter CMD in the search field, then right click on the first result, select “Run as administrator&&&;quo;

2 Enter (copy and paste) Enter the following command
icacls "%programfiles %Microsoft Office 15" /grant *S-1-15-2-1:(OI)(CI)RX

▲ After the command is run, the prompt processing 1 file is successful, 0 is invalid
After the command is successfully run, you do not have to restart it. The above problems can be fixed.
