Sources of AS Problems


Frequent AS Opening Issues

Microsoft Notepad Isn't There

If you attempt to load your AS file, you experience a message such as "Can't Open AS Files". Usually, this is because you do not have Microsoft Notepad for %%os%% installed. You won't be able to double-click to open your AS because your OS doesn't know what to do with it.


Tip: If you know of another program that can open your AS file, you can try opening it by selecting the application from the programs listed.


Outdated Microsoft Notepad

It is possible that your version of Microsoft Notepad isn't able to open your Adobe ActionScript File file due to incompatibility. You will need to download a newer version of Microsoft Notepad if you don't have the right version. This problem is most common when you have an older version of the software application, and your file was created by a newer version that it cannot recognize.


Tip: Investigate your AS file by right-clicking and selecting "Properties" to find clues on what version you need.


Summary: In either case, the majority of problems opening AS files are related to not having the correct software application installed on your computer.


Other Causes of AS File Opening Problems

Even with the correct version of Microsoft Notepad installed, you can still experience difficulties opening ASs. If you are still having problems opening AS files, there may be other issues that are preventing you from opening these files. Issues that aren't software-related:

  • AS file references in the Windows Registry are broken
  • Corruption of the AS file description inside the Registry
  • Microsoft Notepad or another AS application experienced a flawed installation
  • AS file corruption
  • Your AS is infected with malware
  • AS-related hardware has device drivers that obsolete
  • Insufficient system resources to successfully open Adobe ActionScript File files
