Things To Keep In Mind

Before you decide how to open a Key file, it is vital to understand the format of your KEY. Although, all the programs we have listed above are capable of opening a Key file, however, that doesn’t mean that these programs will be able to open Key files from other programs like Registration or License Key file.

For example, if you have an antivirus program that uses a Key file for registering the software to prove that you have purchased it. In that case, use that antivirus program to open that Key file.

Lightwave is yet another example that uses a Key file for registering 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 you can’t view them, and usually, you don’t need to view them.

As the key files are specific to every program that uses them, you must contact the software developer if your key file or program isn’t working properly. For the rest of the key files, you can use the applications mentioned above to open them.
