Although Windows tries to make the installation or upgrade process as easy as possible, unforeseen problems can occur. A missing or damaged .dll file in Windows (7/8/10) is one such problem. Although many people encounter this problem during an upgrade or installation, it can occur at other times as well.

Sometimes installing or uninstalling drivers or applications can cause this error message, and sometimes it can occur for no apparent reason. .dll files are system files. They are very similar to exe (executable) files. However, they are not directly executed by the user. Instead, various applications on the system use these files to perform various functions.
