Possible problems with the EXTENSIONS/JEF format files
The inability to open and operate the EXTENSIONS/JEF 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/JEF file which is being opened
- Incorrect links to the EXTENSIONS/JEF file in registry entries.
- Accidental deletion of the description of the EXTENSIONS/JEF from the Windows registry
- Incomplete installation of an application that supports the EXTENSIONS/JEF format
- The EXTENSIONS/JEF 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/JEF file.
- Drivers of equipment used by the computer to open a EXTENSIONS/JEF file are out of date.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/JEF file should operate with your programs without any problem. If the problem with the EXTENSIONS/JEF 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/JEF file. In this case, the only you can do is to ask for assistance of a professional staff.
