Upgrade Win8.1 Click Setup.exe to not support this upgrade path

Users who are keen on the new system, after seeing the new version of Win8, will be eager to upgrade to Win8.1. But some users are upgrading I have encountered difficulties. Clicking Setup.exe to upgrade the installation failed, and the error message "This upgrade path is not supported" appears. This is generally caused by the wrong directory of the system installation files. How to solve it?

The method is as follows:

1. The safer method is to install the Win8.1 installation image ISO. The file below is extracted to the root directory of a disk. The root directory means that we open my computer and then open the root directory. For example, your Setup.exe file should be in the path E:\\setup.exe. under.

2, the installation file can not be put into the C drive, can not be put into the U disk, can not be driven in virtual light.

3, the installation file can not be placed in the Chinese directory.

The above is the solution to upgrade to Win8.1 system "do not support this upgrade path". Of course, there may be other problems during the upgrade process, such as the prompt 0x80004003 error, etc., friends and friends pay more attention to it.
