Common CELX Opening Problems

Microsoft Notepad Isn't There

When trying to open your CELX file, you get the error "Can't Open CELX File Type". Generally, this is experienced in %%os%% because Microsoft Notepad isn't installed on your PC. Your operating system cannot associate your CELX with Microsoft Notepad, so double-clicking the file won't work.


Tip: If you don't have Microsoft Notepad installed, and you know of another program to open your CELX file, you can try opening it by selecting from the programs listed under "Show Apps".


Microsoft Notepad is Out-of-Date

In other instances, your Celestia Script File file version may not be supported by your version of Microsoft Notepad. Visit the Microsoft Corporation website to download (or purchase) the latest version of Microsoft Notepad. Your Celestia Script File file was probably created by a newer release of Microsoft Notepad than what's currently installed your computer.


Tip: Right-clicking on your CELX, then clicking "Properties" (Windows) or "Get Info" (Mac), can provide clues about your file version.


Primarily, problems experienced when opening CELX files are due to having the incorrect version of Microsoft Notepad installed on your computer.
