Upgrading to Windows 8 can be tricky, especially dealing with missing Dll files.

In this case, you can restore the missing Dll file and/or apply some tricks which help fix the error.
Look at the below mentioned fixes and fix the error. Perform one step at a time as the each one is designed to help fix the error.
Step 1: Disconnect External Devices
Disconnect any external device like router, wireless printer, gaming console, or TV etc. (except mouse and keyboard) from your computer to smoothen the Windows 8 upgrade. While installing Windows 8, external devices, specially gaming consoles like XBOX 360, PlayStation etc. create problems.
Step 2: Disable Antivirus/Firewall
Antivirus or a firewall program restricts the Windows 8 installation file from running as it considers it as a file trying to intrude into your computer’s security. By disabling the antivirus or firewall program you will be able to remove the security restrictions and run the file properly. Once the Windows 8 installation completes, you can re-enable your antivirus or firewall software to protect your computer.
In certain cases, it has been observed that uninstalling the antivirus/firewall program has let the Windows 8 upgrade completed successfully. You may try to do so but don’t forget to re-install your security software on to your computer once the upgrade is done.
Step 3: Register Missing Dll File
Though it’s an easy procedure but it requires that you know the name of the missing DLL file. To register a missing Dll file, open Command Prompt and type “regsvr32 <dll file name>” (without quotes) and hit Enter. Make sure that you are in the root directory of the system to register the file. You will have to reach inside the root directory to do so. For example the root directory is C:\ and the path you see on Command Prompt is C:\Windows\system32\. To get inside the C:\ drive, you will type “cd” and hit Enter. Continue this command until you just see C:\ on screen.
Step 4: Download Windows Updates and other Software Updates
Outdated operating system version and driver software may lead to the missing Dll file error. Download Windows updates and also install the latest version of applications and programs on your computer. also update driver software for your external devices despite that they should have been disconnected.
Step 4: Run System File Checker Tool
Bring up Command Prompt and run the System File Checker command. Type “sfc /scannow” (without quotes) on the Command Prompt screen and hit Enter. This may take some time for the tool to scan for broken files and fix them. After the tool has repaired the broken files, install Windows updates to download the latest files.
