CATOM File Extension

How to open CATOM file?

After double-clicking on the unknown file icon, the system should open it in the default software that supports it. If this does not happen, download and install the Chief Architect software and then manually associate the file with it.

Step 1. Download and install Chief Architect

If there is no Chief Architect or similar software in the system that supports files with the CATOM extension, you must first download and install it. Below you will find a list of the most-used applications that work with CATOM. After going to the subpage of the program you will find a link to the developer's website, where you can safely download the software installer.

Step 2. Associate Chief Architect with the CATOM file extension

If the user already has one of the applications installed, the next step will be to associate it with the file extension CATOM. This can be done in two ways - one is to manually edit the Windows Registry and HKEY_CLASSES_ROOT keys. The second way is simpler and definitely recommended for less advanced users.

• Right click on the unknown CATOM file you want to open
• Select "Open with" from the menu
• Click "Choose another application"
• Click "More applications"
• Click "Find more applications on this PC" and indicate the installation location of the appropriate program
• Finally, select the "Always use the selected program to open CATOM files" option and confirm the whole operation.

Remember! Manually editing the system registry is only recommended for advanced users, and changes made to it without proper knowledge may result in damage to the system.

Step 3. Check out other possible problems related to CATOM files.

Sometimes it happens that despite having the right application and the correct configuration, there are still problems with opening the CATOM files. You should then find out what is the reason of the problem.

• Check if the CATOM file is not infected - When the file CATOM is infected with a virus or malware, it probably will not be able to be opened correctly. In this case, scan the CATOM file and take the actions recommended by the antivirus program installed on the system. Most often it is disinfection or deletion of an infected file.
• Check if you, as the operating system user, have appropriate permissions to work with the file CATOM
• Check if the icon is an element of the correct file but not only a shortcut to the location where the CATOM file no longer exists.
• Check that the system has the necessary resources to run the Chief Architect application and open the CATOM file.
• Check if the file is complete - Sometimes it happens that the CATOM file was not copied completely from the external Flash memory, or downloaded from the Internet. When the file is incomplete, it is not possible to open it correctly. In this case, please download or copy the file CATOM again.

Step 4. Contact an IT expert

When all of the above methods have failed, it remains to contact an IT specialist or developers of the CHIEF ARCHITECT program.
