Possible problems with the EXTENSIONS/3MM format files
The inability to open and operate the EXTENSIONS/3MM 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/3MM file which is being opened
- Incorrect links to the EXTENSIONS/3MM file in registry entries.
- Accidental deletion of the description of the EXTENSIONS/3MM from the Windows registry
- Incomplete installation of an application that supports the EXTENSIONS/3MM format
- The EXTENSIONS/3MM 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/3MM file.
- Drivers of equipment used by the computer to open a EXTENSIONS/3MM file are out of date.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/3MM file should operate with your programs without any problem. If the problem with the EXTENSIONS/3MM 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/3MM file. In this case, the only you can do is to ask for assistance of a professional staff.
