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- Drivers of equipment used by the computer to open a EXTENSIONS/HDM file are out of date.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