After installing Visual Apl, I tried to save a Visual APL Console application, without any code except system generated code but I get an error,

"The operation could not be completed. No such interface supported."

Can someone help.

Thanks!

I am having the same problem - it is irrespective of the Visual APL template used - whenever I try to save the session (and all my work) in Visual Studio 2005, I get the same message.  Running Visual Studio 2005 (with all the latest patches), Visual APL V1.0.7008, Vista (with all the latest patches). 

Visual Studio has no problem if it is a VB or C# project getting saved.

I am currently using MS Vista [ultimate] and MS VS2005 and VisualAPL [professional] and cannot duplicate this problem.

Are you using VisualAPL Express [which has an incorporated expiry date] or a production license, such as VisualAPL Desktop or VisualAPL Professional?
