Step 4. Check for the following problems with the MTKEY file

The problem may also be with the file itself if the above steps don't work. The most common file problems are:

Very often, the file may be size 0 or incomplete. Usually this applies to MTKEY files downloaded from the Internet in case the download did not finish properly. Downloading the file again should fix the problem.
The most common cause here is computer viruses. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the MTKEY file that we want to open. Sometimes virus-infected MTKEY files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the MTKEY file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Depending on the type of file, it is necessary to repair it accordingly. Sometimes the program itself has options to repair the most popular MTKEY file corruption. The easiest way is to restore the file from a backup, if there is one, or contact proDAD Inc.
The program indicates that the file is encrypted or corrupted. The encrypted MTKEY files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. It is best to move MTKEY to a different directory.
This can happen on a file that does not support multiple access. In this case, the MTKEY file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file MTKEY to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
