Typical A4L Opening Challenges

Adobe Authorware Isn't There

If you attempt to load your A4L file, you experience a message such as "Can't Open A4L Files". Customarily, this means that Adobe Authorware is not installed on %%os%%. You won't be able to double-click to open your A4L because your OS doesn't know what to do with it.

Tip: If you know of another program that can open your A4L file, you can try opening it by selecting the application from the programs listed.

Adobe Authorware is Out-of-Date

It is possible that your version of Adobe Authorware isn't able to open your Authorware 4 Library file due to incompatibility. If you've got the wrong version of Adobe Authorware installed, you'll need to install the correct 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: Find clues on the correct software version by right-clicking your A4L file and clicking "Properties".

Conclusion: The majority of A4L file opening issues are due to not having the correct Adobe Authorware version installed.
