Although all the programs we have listed above are capable of opening a key file, however, this does not mean that these programs will be able to open key files from other programs such as registration or license key file.

For example, if you have an antivirus program that uses a key file to register the software to prove that you have purchased it. If so, use that antivirus program to open that Key file.

Lightwave is another example that uses a Key file to register it as a legal copy. If it is a license key file, you can read the license information with Notepad or any other text editor. Registration key files are often encrypted and cannot be viewed and usually need not be viewed.

Since key files are specific to each program that uses them, you should contact the software developer if your key file or program is not working properly. For the rest of the key files, you can use the applications mentioned above to open them.
