Possible problems with the EXTENSIONS/KTN format files
The inability to open and operate the EXTENSIONS/KTN file does not necessarily mean that you do not have an appropriate software installed on your computer. There may be other problems that also block our ability to operate the file. Below is a list of possible problems.
- Corruption of a EXTENSIONS/KTN file which is being opened
- Incorrect links to the EXTENSIONS/KTN file in registry entries.
- Accidental deletion of the description of the EXTENSIONS/KTN from the Windows registry
- Incomplete installation of an application that supports the EXTENSIONS/KTN format
- The EXTENSIONS/KTN file which is being opened is infected with an undesirable malware.
- The computer does not have enough hardware resources to cope with the opening of the EXTENSIONS/KTN file.
- Drivers of equipment used by the computer to open a EXTENSIONS/KTN file are out of date.
If you are sure that all of these reasons do not exist in your case (or have already been eliminated), the EXTENSIONS/KTN file should operate with your programs without any problem. If the problem with the EXTENSIONS/KTN file has not been solved, it may be due to the fact that in this case there is also another rare problem with the EXTENSIONS/KTN file. In this case, the only you can do is to ask for assistance of a professional staff.
