Step 3 – Clean Out The Registry

One of the big causes of Rpcrt4.dll errors is through the “registry” database of your computer. This is a large database which stores vital information & settings for your PC, and is used continually to help Windows to read the files, settings & options that it needs to run. Although the registry is one of the most important parts of every Windows system, it’s continually causing a large number of problems thanks to the way it will often become corrupted and unreadable. This is the cause behind many rpcrt4.dll errors, and needs to be resolved by using a reliable “registry cleaner” application.

This step is best completed by downloading RegAce System Suite, and letting it clean out any of the problems that your system may have inside.
