How to open COX file?

An often recurring problem with Click & Create Extension is that COX is not associated with the correct program file. This causes the file COX to open by system applications not designed for this purpose, or to display a message that there is no associated program. This problem can be easily remedied.

The first thing you should do is just "doubleclick" on the COX 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 Multimedia Fusion

The first step is to check if the computer has the Multimedia Fusion program installed. This can be achieved by typing Multimedia Fusion into the operating system search engine. If it is not, installation may solve the problem, as most applications create file associations during installation. Below you will find a list of applications that support COX files.

Programs to open COX file

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

Step 2. Create association of Multimedia Fusion with COX files

However, it may happen that the application itself does not cause the COX file to open in the Multimedia Fusion application, but you can set it manually. It is most convenient to call the context menu with the right mouse button and select Properties. 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. It may happen that in the next window there will be no appropriate program - however, this can be corrected with the "Browse" option where you should manually indicate the program location. The "always use the selected program ..." field will set the Multimedia Fusion application as the default for handling the COX file.

Step 3. Update Multimedia Fusion to the latest version

The fault may also lie with the Multimedia Fusion program, it is possible that Click & Create Extension requires a newer version of the program. This can be done using the application (if it provides such options) or from the ClickTeam website and install the latest version.

Step 4. Check for the following problems with the COX 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:

The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the COX file. The file should be downloaded again, making sure that the process has finished correctly.
The operating system may be infected with a computer virus. Perform a virus scan using available and up-to-date anti-virus software. Alternatively, you can use the scanners available online. The scan should cover the entire computer, not only the COX file that we want to open. However, remember that not every infected COX file can be recovered, so it is important to take care of regular backups.
Older version of COX file may not always be supported by the latest software version. 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 this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged COX files. The easiest way is to restore the file from a backup, if there is one, or contact Clickteam
The program indicates that the file is encrypted or corrupted. The encrypted file COX 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. The problem is only writing to the file, not reading it. If possible, you can try to move the COX file to another location.
This problem only occurs with more complex files. In this case, the COX 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 COX to close. Some anti-virus or backup software may occupy the COX file for a certain period of time. If nothing helps, please reset the device.
