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- Drivers of equipment used by the computer to open a EXTENSIONS/CTB file are out of date.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