How to open ONB file?

The first thing you should do is just "doubleclick" on the ONB file icon you want to open. If the operating system has an appropriate application to support it and there is also an association between the file and the program, the file should be opened.
Step 1. Install OpenModelica

Programs to open ONB file
Remember to download programs supporting ONB files only from verified and safe sources. We suggest using the websites of software developers.
Step 2. Create association of OpenModelica with ONB files
If the application is or has been freshly installed, but the ONB file still does not use the OpenModelica program, it means no association. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. The displayed window will contain information about the program that supports this type of file. Using the "Change" button we can select the desired program. The program should be visible in the window, otherwise it should be selected manually using the "Browse" button and the program installation directory should be indicated. Checking the "Always use the selected program ..." box will permanently associate the ONB file with the OpenModelica program.
Step 3. Update OpenModelica to the latest version
If, despite the association of the OpenModelica program with the OpenModelica Document Format file, the file still does not open, check the program version and possibly update it to the newest version.
Step 4. Check for the following problems with the ONB file
If the above steps do not help, you can assume that the file itself is not correct. This could be due to the file itself, the cleanest issues are:
Very often, the file may be size 0 or incomplete. This is most often caused by a problem while downloading the ONB file. The only repair option is to download the file again.
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. Alternatively, you can use the scanners available online. However, it is important to scan the entire system, not only the file ONB or the program directory. Sometimes virus-infected ONB files cannot be recovered, so make a backup in advance.
A typical compatibility error - the program does not support the older version of the ONB file. These problems are known and are often very easy to fix using the software developers's website.
The file may be corrupted in a number of ways. Repairing is very dependent on the file type. Some programs offer the ability to automatically repair ONB file corruption.
When reading, a message appears that the file was encrypted or corrupted. The encrypted file ONB 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.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. The problem is only writing to the file, not reading it. If possible, you can try to move the ONB file to another location.
This problem only occurs with more complex files. In this case, the ONB file is blocked by the first application to open it. Just close unnecessary programs. Sometimes you have to wait for the session to the file ONB to close. Some anti-virus or backup software may occupy the ONB file for a certain period of time. If nothing helps, please reset the device.
