Win7 upgrade after Win10 Office 2013 file can not be opened

After the Win7 system was upgraded to the official version of Win10, the files created by the original Office 2013 could 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: This file has a problem and cannot be opened.

• There are three cases for PowerPoint:

1 The application does not start correctly

2PowerPoint found that <filename> has a problem

3 sorry , PowerPoint can not read <file name>

In fact, this problem has nothing to do with the file itself to be opened, but Office 2013 has some "after the arrival of Windows10", there is compatibility. The problem is that it is not working properly.

There are two solutions:

1. Use the Office 2013 CD or ISO image to repair existing software. If there is no CD-ROM and CD-ROM, you can use the virtual CD-ROM drive (click to download) to load the ISO image. After opening the CD (or image), double-click the setup.exe installer to fix it.

▲Double-click setup.exe to run Office 2013 installer

2. If there is no CD and image, you can enter the command in the “Command Prompt” command, as follows:

1Enter CMD in the Cortana search bar, then right click on the first result, select “Run as administrator&>

2 Enter (copy and paste) the following command and enter

icacls "%programfiles%Microsoft Office 15" /grant *S-1-15-2-1:(OI)(CI)RX

▲After the command is run, the prompt processing is successful 1 File, failed 0

After the command is successfully run, you do not need to restart, the above problems can be fixed.
