Issue: How to fix “Mpr.dll is either not designed for Windows or contains an error”?

Hello. Recently I started seeing the “Mpr.dll is either not designed for Windows or contains an error” message when trying to install applications. What should I do?

Solved Answer

Recently, some Windows users have run into serious issues. People report witnessing “Mpr.dll is either not designed for Windows or contains an error” message when trying to install applications or connect to the Internet. The error was reported to appear after corrupt software installations.

And there is no surprise there as missing DLL (Dynamic-Link Library)[1] errors most often appear after corrupted updates, and installations. These system files contain code and data that can be used by multiple programs at the same time. That is why users may fail to open multiple programs and receive the same error.

Additionally, accidental deletion is more common than you may think. Users often go to places they should not, like the registry,[2] and delete important system files without realizing the repercussions. Do not delete any files if you are not sure what they are for.

Besides, privacy-focused browsers like Tor is are not an optimal choice due to diminished connection speeds.
