Win8.1 Installation Failure error 0x80004005 how to solve

　　Workaround One:

1, click Start, turn to run, type cmd in the Open box, and then click OK.

2. At the command prompt, type the following commands. Press the ENTER key after each line:

regsvr32 Softpub.dll

regsvr32 Wintrust.dll

regsvr32 Initpki.dll

3, click "OK".

4, restart the computer.

This may be possible due to improper configuration of the dynamic-link library files, a firewall between the computer and the Internet that does not allow HTTPS (SSL) connections, and so on, to fix both problems by using the steps above.

　　Workaround Two:

In addition, if the direct upgrade does not work, we recommend that you download the image File New installation, which can also solve such problems.
