PHYSAO File Complications

Typical PHYSAO Opening Challenges

Missing Aleph One

You encounter an error message such as "%%os%% Can't Open PHYSAO Files" when trying to open your PHYSAO. If so, it typically means that you don't have Aleph One installed for %%os%%. You won't be able to double-click to open your PHYSAO because your OS doesn't know what to do with it.

Tip: Another PHYSAO-related program can be selected to open the file by clicking "Show Apps" and finding the application.

Aleph One Requires Update

Sometimes your installed version of Aleph One won't support your Physics Model file. Download the latest Aleph One version from the Marathon Open Source website to ensure you have the correct one installed. Most of the time your Physics Model file was created by a newer Aleph One than what you have installed.

Tip: Sometimes you can get a clue about the version of PHYSAO file you have by right clicking on the file, then clicking on "Properties" (Windows) or "Get Info" (Mac OSX).

Conclusion: The majority of PHYSAO file opening issues are due to not having the correct Aleph One version installed.

More Causes of Problems Opening PHYSAOs

Assuming you have the right Aleph One version installed, other problems can prevent you from opening PHYSAO files. There can be other issues - unrelated to software - preventing you from opening PHYSAO files. Problems unrelated to software:

• Your PHYSAO can't be loaded properly (file corruption)
• Malware-tainted PHYSAO file can't be opened
• Drivers associated with PHYSAO software need to be updated
