How to open MOPINT file?

An often recurring problem with Mopac Internal Chemical Modeller Input is that MOPINT is not associated with the correct program file.

Step 2. Create association of MOPAC with MOPINT files

If the application is or has been freshly installed, but the MOPINT file still does not use the MOPAC program, it means no association. This option is available from the level of Properties of a specific file available in the context menu. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can set the program to handle this type. If there is no software on the list, simply select "Browse" and manually select the directory where the application is installed. Checking the "Always use the selected program ..." box will permanently associate the MOPINT file with the MOPAC program.

Step 3. Update MOPAC to the latest version

The fault may also lie with the MOPAC program, it is possible that Mopac Internal Chemical Modeller Input requires a newer version of the program.

Step 4. Check for the following problems with the MOPINT file

If the above steps do not help, you can assume that the file itself is not correct. File problems can be divided into the following:

Very often, the file may be size 0 or incomplete. This suggests truncating the MOPINT file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. A quick virus scan using an up-to-date antivirus program should clear up any doubts. Some antivirus vendors also provide free online scanners. For the best results, we will scan the entire operating system, not just our MOPINT file. Sometimes virus-infected MOPINT files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the MOPINT file. Help should be sought from the software developer, as they usually recommend using free file converters or installing an older version of the program.
There can be many reasons for the failure. The repair method must be adapted to the type of file and damage. Sometimes the program itself has options to repair the most popular MOPINT file corruption.
The program indicates that the file is encrypted or corrupted. The encrypted file MOPINT except for the special designation, works normally, but only on the device where it was encrypted, before transferring it to another machine, decryption is required.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. While there is usually no problem reading such a file, it may not be possible to save it. Copying the MOPINT file to another location will fix the problem.
This problem usually affects more complex files. You may find that another program you are using is preventing you from working with the file. Closing other programs should help. If the error persists after closing other programs, wait for a while. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If the problem persists, restart the machine.
