What is CELX file?

The file with the extension CELX is the Executable Files file type. It was designed by Celestia Development Team. Additionally, the Executable Files category contains 140 of other files. Celestia Script is most often found on 3 operating systems. Although it can be found with greater or lesser success on any operating system, it will only be useful on Linux, Mac OS, Windows.

How to open CELX file?

The main problem with Celestia Script is that the CELX file is incorrectly associated with programs. This is manifested by the fact that CELX files open in unusual applications or do not have an assigned program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the CELX 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 Celestia

An often overlooked issue is to make sure that Celestia is installed on the computer. This can be achieved by typing Celestia into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Later in this article you will find a list of programs that can open CELX files.

Programs to open CELX file

Remember to download programs supporting CELX files only from verified and safe sources. We suggest using the websites of software developers.

Step 2. Create association of Celestia with CELX files

However, it may happen that the application itself does not cause the CELX file to open in the Celestia application, but you can set it manually. The association can be created using the drop-down list available by right-clicking on the file and selecting Properties. Information about the file and the program that the file is associated with are available here. 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 CELX file with the Celestia program.

Step 3. Update Celestia to the latest version

If, despite the association of the Celestia program with the Celestia Script file, the file still does not open, check the program version and possibly update it to the newest version. In this case, use the Celestia Development Team website or update the program from the application.

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

The problem may also be with the file itself if the above steps don't work. This could be due to the file itself, the cleanest issues are:

The CELX file may be unusually small compared to the original file. This suggests truncating the CELX file contents when downloading or copying. The file should be downloaded again, making sure that the process has finished correctly.
The computer may have fallen victim to a computer virus or hacker. A quick virus scan using an up-to-date antivirus program should clear up any doubts. If this is not possible, you can use the online scanner. The scan should cover the entire computer, not only the CELX file that we want to open. Sometimes virus-infected CELX files cannot be recovered, so make a backup in advance.
Older version of CELX file may not always be supported by the latest software version. On their websites, developers usually offer free solutions to such problems, e.g. in the form of a conversion program or an older version of the program.
The file may be corrupted in a number of ways. The repair method must be adapted to the type of file and damage. Some programs offer the ability to automatically repair CELX file corruption. The easiest way is to restore the file from a backup, if there is one, or contact Celestia Development Team
The program can also signal the fact of encryption. The encrypted CELX files can be used by the device on which they were encrypted, on any other device it is required to have the appropriate cryptographic key and decrypt the file before its recovery.
Some operating systems do not allow file operations in certain locations, eg in system directories or directly on the system drive. These directories are write-protected to them and it's very hard to fix this problem. It is best to move CELX to a different directory.
This can happen on a file that does not support multiple access. You may find that another program you are using is preventing you from working with the file. Just close unnecessary programs. Sometimes you have to wait for the session to the file CELX to close. However, some background programs may block the CELX file while scanning. If this does not work either, restart the device.
