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- Drivers of equipment used by the computer to open a EXTENSIONS/SIDX file are out of date.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