.APL file is related to Cantura client.

You need centura framework to open that file.
If you are trying to open it 7\7.5 Internet Project Explorer (IPE), I believe you can open it as it has required framework there.

Hi,

In App 7/7.5 Developer Desktops, open the Internet Project Explorer (IPE), under Foundation Tools links you will find Develop Tool.

You can open the APL file from there. You can compile and see whether there are any Errors or no Errors.
