Recommended fix if you are experiencing apackeng.dll error messages:

DLL (Dynamic Link Library) files contain computer code and resources that can be used by multiple programs at the same time. This uses less system memory and helps your computer system run more efficiently. DLL files give program developers the ability to reuse code to add features to several programs without the need to write new code for each program.

There are many programs that require DLL files to function properly so when one of them is damaged or missing it will cause program crashes and poor system performance.

To fix these problems the user must replace the damaged file with a valid working version. If a working version cannot be found the user may perform a reinstallation of their operating system.
