Win8.1 installation software prompts that the registered key set is invalid and cannot be installed

It has been around for a while with the Win8.1 system. Occasionally, when you install some software, you will be prompted that the registered key set is invalid, which will make it impossible to install.

I tried to install a few software, including the Bing Dictionary and the Diablo Big Box plugin, and other software such as the 115 network disk will not. How to solve this problem?

This may be caused by a serious problem with the system components. It is best to perform the operation of “recovering the computer without affecting the file” and recovering the system with minimal impact. To solve the problem.

The method is as follows:

1. Move the mouse to the lower right corner of the screen, call up the Charm column, and click the gear shape to set the ” button.

2.Click “Change Computer Settings&

3.Click “Update & Restore" 

4.Click “Restore”

5. Click “Start” in the corresponding location according to your needs.

The above is the solution for prompting the registered key set to be invalid when the Win8.1 system is installed. The common method of system components is difficult to solve. It can only be solved by restoring the computer without affecting the file.
