Troubleshoot A3M Files

Common A3M Opening Problems

Adobe Authorware Disappeared

You attempt to load your A3M file and get an error such as "%%os%% Can't Open The A3M File Extension". When this happens, it is commonly due to Adobe Authorware missing in %%os%%. The typical path of opening your A3M with a double-click won't work because %%os%% cannot make the program connection.

Tip: If you have another software that you know opens A3M files, you can select it by hitting the "Show Apps" button.

Adobe Authorware Requires Update

Occasionally, you might have an outdated version of Adobe Authorware installed that's incompatible with your Authorware 3 Macintosh File type. You will need to download a newer version of Adobe Authorware if you don't have the right version. This issue mainly occurs when your Authorware 3 Macintosh File file was created by a newer version of Adobe Authorware than you have on your PC.

Tip: Find clues on the correct software version by right-clicking your A3M file and clicking "Properties".

Conclusion: The majority of A3M file opening issues are due to not having the correct Adobe Authorware version installed.
