Why do some of my DLL files disappear suddenly?
As we have explained above in this article, one DLL file is shared among many programs. Hence, sometimes when you uninstall a program using third-party software, it may delete all the files including the DLL files. After this, you will receive the DLL missing error on all those programs which use that particular DLL file that has been deleted.
Why do I receive a message Install failed, files in use, or insufficient permission while installing a DLL file?
The message clearly indicates that the DLL file that you are installing is currently in use. This means that the file already exists on your computer and cannot be overwritten. To solve this error, reinstall the program in which you are getting the DLL missing error.
